Title: Proficient Data Gathering by Mobile Agent using JADE 

Author Name: Karthikeyan.S, S. Jayashri 

Synopsis: 

The advancement in wireless communication is achieving a tremendous increase of low cost wireless sensor network. The activities around are sensed from the environment, gathered and transmitted to intended users.  This paper focuses for a high efficient data gathering through the agent mobility with routing and event driven mechanism. Here the agent move towards the subhead of the event driven data, replacing the sink mobility and thereby reducing the energy consumption of the network. Based on the data gathering algorithm, the sub head chooses the closest fixed nodes along the path as roots to build a routing tree dynamically. The sub-heads perform data aggregation through direct communication area (DCA) between trajectories L1 and L2, multihop communication area (MCA) and sent to sink reversely by the tree. This paper has used priority based routing in which the sub heads are set with a priority according to which the agent moves. Since the energy consumption is minimized and the network lifetime is improved, the mobile agent-based data gathering protocol is better than others. Added to the agent based data gathering the priority based routing also increases the network lifetime.

Title: Optimized Seamless Handoff Latency in Wireless Networks. 

Author Name: B. Jaiganesh, R. Ramachandran 

Synopsis: 

FHMIPv6 was only designed to provide local mobility management, it still suffers from a lengthy handoff latency and packet loss during the handoff process when Mobile Node(MN) moves to a new network or different technology with a very high speed. Even more, since detecting MNs' detachment  and  attachment  events  remains  challenging  in  many  wireless  networks,  increase handoff latency. Such long handoff latency might disrupt seamless communication session and some interruptions. For example, handoff that might reach hundreds of milliseconds would not be acceptable for delay-sensitive applications like video streaming and video conference.

The use of the Media Independent Information Service (MIIS) in the IEEE 802.21 Media Independent Handover (MIH) framework to improve handoff performance for Fast Handoff in hierarchical Mobile IPv6 is explored. Integrating FHMIPv6 and MIH has been the concern of the proposal in optimizing handoff latency. This solution tries to preserve the quality of the streaming video upon each handoff, recovering the user video session spoiled by the high delay caused by MIP. The performance of the handoff latency, packet loss, throughput and video transmission quality were simulated tool using NS-2.

A Performance Comparison of OLSR Routing Protocols for Manet

Vol. 1 No. 2

Title: A Performance Comparison of OLSR Routing Protocols for Manet 

 Author Name: Sammy Soban 

 Synopsis: 

 All the nodes in the Mobile ad hoc networks (MANETs) are decentralized with no fixed infrastructure as well as each of them acts as a node, a router and transmit the packets that are not in a range. Because of these characteristics, paths connecting to the source nodes with destinations may very unstable and go down at any time, making communication over ad hoc networks difficult. The Optimized Link State Routing Protocol (OLSR) is an IP routing protocol which is optimized for mobile ad-hoc networks. OLSR is a proactive link-state routing protocol which uses Hello and Topology Control (TC) messages to discover and then disseminate link state information throughout the mobile ad-hoc network. Individual nodes use this topology information to compute next hop destinations for all nodes in the network using shortest hop forwarding paths. In this paper we compared the classic OLSR algorithm with the multipath OLSR. Simulation results show that MOLSR achieves lower delay and higher packet delivery ratio, throughput than the classic OLSR.

Title: Implementation of Adaptive Event based Packet Scheduler for RREQ Mechanism in MANET 

Author Name: LAKSHMI SANKARAN, Radha 

Synopsis: 

The adaptive event based packet scheduler for ad-hoc on demand distance vector protocol (AEBPS) method support among the buffer manager and scheduler for each and every node in order that event node packets can be distinguished from the non event node packets. Because of the presence of flooding attack might corrupt the performance by utilizing the useful resources which result in congestion in the network. In MANET if AEBPS is adapted this provides most favorable solution for all the nodes which are affected by RREQ flooding mechanism. The AEBPS may vividly induce a reactive solution that could manage the queues where the packets are stored before scheduling. The simulation of this model was run using ns-2.26 which was compared   with adaptive buffer scheduler, the results compromise that AEBPS increases packet delivery ratio but decreases control overhead and total overhead.

Title: Efficient Channel Estimation for MIMO-OFDM Systems With Joint Carrier Frequency Offset using UKF 

Author Name: M. Jeya Prabha, J. Nalini 

Synopsis: 

MIMO antennas with orthogonal frequency-division multiplexing (OFDM) provide high data rates and are robust to multipath delay in wireless communications. In this paper, we propose a complete algorithm capable of jointly estimating the CFO and the path CA by taking into account the fast variation of each path CA in a MIMO environment. In olden approach, an algorithm based on extended Kalman ?ltering (EKF) and the equivalent discrete-time channel model, but the fast time variation of the channel was not taken into account. The extended Kalman filter in general is not an optimal estimator (of course it is optimal if the measurement and the state transition model are both linear, as in that case the extended Kalman filter is identical to the regular one). In addition, if the initial estimate of the state is wrong, or if the process is modeled incorrectly, the filter may quickly diverge, owing to its linearization. An improvement to the extended Kalman filter led to the development of the Unscented Kalman filter (UKF), also a nonlinear filter. In the UKF, the probability density is approximated by the nonlinear transformation of a random variable, which returns much more accurate results than the first-order Taylor expansion of the nonlinear functions in the EKF. The approximation utilizes a set of sample points, which guarantees accuracy with the posterior mean and covariance to the second order for any nonlinearity. The UKF tends to be more robust and more accurate than the EKF in its estimation of error.

Synopsis: 

Wireless network has become increasingly popular in the past few decades, particularly within the 1990’s when they are being adapted to enable mobility and wireless devices become popular. In the near future, a pervasive computing environment can be expected based on the recent progresses and advances in computing and communication technologies. Next generation of mobile communications will include both prestigious infrastructured wireless networks and novel infrastructure less mobile ad hoc networks (MANETs). A MANET is a collection of wireless nodes that can dynamically form a network to exchange information without using any pre-existing fixed network infrastructure. This paper describes the fundamental problems of ad hoc networking by giving it related research background including the concept, features, and its applications in future wireless network especially in the hostile military environment. By combining two hottest wireless network topics, 4G (the fourth generation of cellular communication systems) and MANET, we explore potentials as well as foreseeable challenges to the wireless communications in the future battlefield. Special attention is paid on network layer routing strategy of MANET and key research issues include new X-cast routing algorithms, security & reliability schemes, QoS model, and mechanisms for interworking with outside IP networks.
