In this article, we propose a novel routing algorithm for wireless sensor network, which achieves uniform energy depletion across all the nodes and thus leading to prolonged network lifetime. The proposed algorithm, divides the Region of Interest into virtual zones, each having some designated cluster head nodes. In the entire process, a node can either be a part of a cluster or it may remain as an independent entity. A non-cluster member transmits its data to next hop node using IRPIntelligent Routing Process (based on the trade-off between the residual energy of itself as well as its neighbor, and therequired energy to transmit packets to its neighbor). If on the transmission path, some cluster member is elected as a next hop, it rejects IRP and transmits the packets to cluster head, which later forwards them to sink (adopting multihop communication among cluster heads). Routing is not solely performed using clusters, rather they aid the overall routing process, hence this protocol is named as Cluster Aided Multipath Routing (CAMP). CAMP has been compared with various sensor network routing protocols, viz., LEACH, PEGASIS, DIRECT TRANSMISSION, CEED, and CBMR. It is found that the proposed algorithm outperformed them in network lifetime, energy consumption and coverage ratio.
A wireless sensor network (WSN) consists of tiny, low powered sensors communicating with each other possibly through multi-hop wireless links and collaborating to accomplish a common task . They have naturally emerged as enabling infrastructures for cyber-physical applications that closely interact with external stimulus. Homeland security, physical infrastructures monitoring, health care, building or factory automation are just a few elucidative examples of how these emerging technologies will impact our daily life and society at large . Sensor nodes are small micro-electromechanical systems (MEMS) devices , which operate on limited power supplies for pervasive computing and Internet of Things which globally interconnect smart devices and sensor networks.
