Abstract
Balancing the energy efficiency and path reliability is the biggest task in Wireless Sensor Networks (WSNs). The existing schemes fail to improve the network performance. In this research, a dynamic Multi-hop Energy Efficient Routing Protocol (DMEERP) is proposed to balance the path reliability ratio and energy consumption. It contains three sections. In first section, network model and basic assumptions were made for cluster creation and multi-hop route establishment. The Super Cluster Head (SCH) stores and maintains all records of CH and cluster members. The node activation and weight factor are estimated to obtain new cluster head if existing fails. In second section, path reliability ratio is estimated for routing the packets quickly without making more packet loss. In third section, energy model is implemented based on channel capacity model. The simulation analysis are made using network simulator (NS 2.33) in terms of packet delivery ratio, network lifetime, data flow, energy consumption, path reliability ratio, control overhead and delay etc.
