Energy Efficient and Fault Tolerant Routing Protocol for Mobile Sensor Network

Abstract

Designing energy efficient and reliable routing protocols for mobility centric Wireless Sensor Networks (WSN) applications such as wildlife monitoring, battlefield surveillance and health monitoring is a great challenge since topology of the network changes frequently. Existing cluster-based routing protocols such for LEACH-Mobile, LEACH-Mobile-Enhanced, CBR-Mobile that are designed for mobile sensor network only consider the energy efficiency of the sensor nodes. Moreover, these protocols allocate extra timeslots using TDMA scheme to accommodate nodes that enter a cluster due to mobility and hence, increases end-to-end delay. In this paper, we propose a Fault Tolerant Clustering Protocol for Mobile WSN (FTCP-MWSN) that is not only energy efficient but also reliable by introducing fault tolerance mechanism. Moreover, FTCP-MWSN does not use any extra timeslot for calculating mobility and thus, reduces end-to-end delay. Simulation results show FTCP-MWSN protocol has more network lifetime, reliability than the existing LEACH-Mobile and LEACH-Mobile-Enhanced protocols.
