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.

1 Introduction Wireless sensor networks (WSNs) have received significant attention in recent years due to their potential applications in military sensing, wildlife tracking, traffic surveillance, health care, environment monitoring, building structure monitoring etc. Due to nature of medium, sensor nodes experience small degree of movement in specific applications.

Wireless sensor network (MWSN) are the special case of WSN similar to MANET but with limited degree of freedom compared to MANET. Due to node mobility, infrastructure changes and multi hop routing becomes challenging. The lifetime of path is low and faults in routing are quite common. But for a network to be usable in many applications, it must deliver a certain level of quality of service. Capacity and quality at each link is different and hence QoS is very difficult. Multimedia content, especially video streams require transmission bandwidth that is orders of magnitude higher than that supported by currently available sensors. For example, the nominal transmission rate of stat
