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.
