Abstract:

Wireless sensor network comprises several small nodes distributed randomly in an area under observation. These nodes sense the assigned physical phenomenon occurring around it and reports back to the base station. WSN is increasingly applied in defense, industrial, health care applications etc. Some applications envisage movement of the nodes. This results in frequent alteration of network topology leading to dynamic network partitioning. Hence, the routing of data from source to sink faces more routing disruptions. Maintaining application specific quality of service (QoS) in terms of Packet delivery ratio in such Mobile wireless sensor network (MWSN) environment is a daunting task. This cannot be achieved by focusing on a solution in only a single layer of sensor network protocol stack. Instead, by incorporating different techniques in each layered OSI protocol stack, a single coherent framework is proposed in this paper. This paper proposes prediction based coding in application layer, opportunistic routing in network layer, Laplacian scaling based on round trip time measurement in session layer. The proposed cross layer solution ensures application specific QoS guaranteed fault tolerance in MWSN.
