Abstract

Mobile wireless sensor network (MWSN) is a wireless ad hoc network that consists of a very large number of tiny sensor nodes communicating with each other in which sensor nodes are either equipped with motors for active mobility or attached to mobile objects for passive mobility. A real–time routing protocol for MWSN is an exciting area of research because messages are delivered according to their end–to–end deadlines. MWSN demands real–time routing in many applications including disasters fighting, forest fire detection and volcanic eruption detection. This paper proposes a novel idea of real–time that provides mobility and load distribution (RTMLD) for MWSN. RTMLD utilised corona mechanism and optimal forwarding metrics to forward the data packet in MWSN. It computes the optimal forwarding node based on RSSI, remaining battery level of sensor nodes and packet delay over one–hop. RTMLD ensures high packet delivery ratio and experiences minimum end–to–end delay in WSN and MWSN compared with baseline routing protocol. RTMLD has been successfully verified through test bed and simulation experiment.
