DREEM-ME: Distributed Regional Energy Efficient Multi-hop Routing Protocol based on Maximum Energy with Mobile Sink in WSNs

Wireless distributed sensor network consists of randomly deployed wireless sensors having low energy assets. These networks can be used for monitoring in a variety of environments. Major problem of these networks is energy constraint and lifetime, so, to overcome these problems different routing protocols and clustering techniques have been introduced. We propose Distributed Regional Energy Efficient Multi-hop Routing Protocol based on Maximum Energy in WSNs (DREEM-ME), which uses a unique technique for clustering to cover these two problems efficiently. Clustering technique of LEACH does not assure a fix number of Cluster Heads (CHs) in each round. Therefore, its behavior is not so appreciable in case of network lifetime. DREEM-ME elects fix number of CHs in each round instead of probabilistic selection of CHs. We also implement the Packet Drop technique in our protocol which makes it more comprehensive and practical. Our simulations and results show that DREEM-ME competes all of its identical protocols.
