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 due to the frequent change of the network topology. Existing cluster-based routing protocols such for LEACH-Mobile, LEACH-Mobile-Enhanced, and CBR-Mobile that are designed for mobile sensor network consider only the energy efficiency of sensor nodes. Moreover, these protocols allocate extra timeslots using TDMA scheme to accommodate nodes that enter a cluster due to mobility and thus, increase the end-to-end data transmission 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. Moreover, FTCP-MWSN does not require any extra timeslot for calculating the mobility of sensor nodes and thus, provides faster data delivery to base station (BS). Simulation results show the FTCP-MWSN protocol has more network lifetime and reliability than the existing LEACH-Mobile and LEACH-Mobile-Enhanced protocols.
