MMLC Mobile Clustering Routing Scheme Based on LEACH in Wireless Sensor Network

Situations that need quick responses, just like monitor of enemy in battlefield or emergency preparedness, the quick response to large amounts of datas bring great challenges to traditional wireless sensor network routing protocol. Most of the routing protocols use a static cluster head node to collect datas from the entire network, resulting in large communication capacity around the cluster head node, causing a greater degree of congestion. Based on the reference of LEACH routing algorithm, combined the dynamic cluster ideas and adding dynamic MDG nodes, the paper presents a MMLC routing protocol model on the basis of LEACH. Simulation results show that MMLC protocol model greatly reduce the communication capacity around the cluster head nodes, shorten delay time of the data transmission to extend the network life cycle.
