Abstract
An energy efficient and reliable routing protocols for mobility centric applications of wireless sensor network (WSN) such as wildlife monitoring, battlefield surveillance and health monitoring is a great challenge since topology of the network changes frequently. Existing cluster-based mobile routing protocols such as ELFCP-MWSN,LEACH-Mobile, LEACH- mobile Enhanced and CBR-Mobile consider only the energy efficiency of the sensor nodes. However ,reliability of routing protocols by incorporating fault tolerance scheme is significantly important to identify the failure of data link and sensor nodes and recover the transmission path. Most existing mobile routing protocols are not designed as fault tolerant. Moreover, existing mobile routing protocols are not location aware and assume that sensor nodes know their coordinates. In this, we enhanced the existing LFCP-MWSN to ELFCP-MWSN in which we reduce network energy consumptions and slightly less end-to-end data transmission delay than the existing LFCP-MWSN.ELFCP-MWSN also incorporates a simple range free approach to localise sensor nodes during cluster formation and every time a sensor moves into another cluster. Simulation results show that ELFCP-MWSN protocol has about 20-25% less network energy consumptions and slightly less end-to-end data transmission delay than the existing LFCP-MWSN , in our study we try to decrease this percentage of energy consumption and more less end-to-end data transmission.
