Performance Evaluation of the DEEC, Teen & EDCS Protocols for Heterogeneous WSNS
نویسنده
چکیده
Wireless Sensor Networks (WSNs) have many sensor nodes having restricted battery, which transmit sensed data to the Base Station that requires high energy consumption. Numerous routing protocols have now been proposed in this regard getting energy efficiency in heterogeneous situations. Though, each protocol is inappropriate for heterogeneous WSNs. Efficiency of WSNs declines as varying the heterogeneity of sensor nodes. This paper has evaluated the performance of varied Distributed EnergyEfficient Clustering based protocols like DEEC, TEEN and EDCS under numerous scenarios; comprising various amount of heterogeneity. MATLAB tool is used for experimental purpose. The comparison has shown that the EDCS has very effective results over other DEEC and TEEN variants because special feature of T-absolute i.e. it treats all heterogeneous sensor nodes with same election probability when each node has lesser energy than T-absolute. The comparative analysis has shown that the EDCS outperforms over the available protocols.
