Scalable M2M routing protocol for energy efficient IoT wireless applications

Machine devices are capable of processing the events captured by sensors and forwarding them through M2M gateway. Non-uniform energy consumption and extensive use of limited energy resources are the common reasons behind developing new energy efficient routing algorithms and protocols. The aim of this paper is to design hybrid routing protocol for M2M sensor network with multiple mobile sink nodes for IoT wireless applications. The proposed scalable energy efficient clustering mechanism will implicitly solve the network scalability, performance degradation and unbalance energy consumption problems. The simulation results showed that using multiple mobile sink nodes and the proposed clustering algorithm improved the energy distribution and prolong network lifetime, more specifically, the percentage difference between the proposed energy efficient routing protocol and the existing routing protocols showed remarkable enhancement about 80% and 92% in terms of the network lifetime and packets delivered to sink nodes respectively.
