Cooperative effort based wireless sensor network clustering algorithm for smart home application

Present research work propose the design of a low energy and high throughput, hierarchical clustering based routing protocol for smart home sensor network application. Proposed protocol perform dynamic cluster head selection based on multiple node characteristics like node residual energy, node distance from sink and node average distance from neighbour nodes. Cluster head distribution is even and results in enhanced network lifetime. Sensor nodes process the sense data using local on-board processors and omit the redundant data from transmission. In this manner, cooperative effort by sensor nodes save significant amount of node transmission energy. Elongated lifetime and reduced data traffic in network reduce data loss rates during transmission and result in high throughput. Wireless channel model and path loss model for indoor residential environment are used for protocol simulation. Simulation is carried using MATLAB tool and results are obtained in terms of network lifetime, stability period, throughput etc. Results, as compared with existing protocols, proves the efficiency of proposed protocol.
