Distance-based Stable Election Protocol (DB-SEP) for Heterogeneous Wireless Sensor Network

Abstract

Preserving the consumed energy of each node for increasing the network lifetime is an important goal that must be considered when developing a routing protocol for wireless sensor networks. The main objective of cluster-based routing protocol is to efficiently maintain the energy consumption of sensor nodes by involving them in multi-hop communication within a cluster and by performing data aggregation and fusion in order to reduce the number of transmitted messages to the base station (sink) and transmission distance of sensor nodes. In this paper we propose a new approach called (DB-SEP) which cluster heads are selected on the basis of their initial energy and their distances between them and the sink. Experimental results show that our approach performs better than the other distributed clustering protocols such as SEP in terms of energy efficiency and lifetime of the network.

A systematic review on heterogeneous routing protocols for wireless sensor network

“…For details of remaining terms, one can refer [24]. The main advantages of this protocol were i) DB-SEP was autonomous and more efficient in energy consumption ii) Simulation results when the other cluatering protocols shows that it extends the network lifetime much more efficiently.…”

“…Said et al [24] proposed Distance Based Stable Election Protocol for HWSNs (DB-SEP). Objective of DB-SEP was to increase the life time of network and to improve energy efficiency.…”

“…DBCP was an extension of DB-SEP [24] by taking full advantages of heterogeneity and these advantages were: i) Better life time ii) No of alive nodes were more in DBCP as compared to pre existing protocols of similar categories iii) Number of packets sent to BS was more in DBCP. Thus throughput of DBCP was more than SEP and LEACH.…”

Energy and Density Aware Clustering (EDAC) to Improve Lifetime and Connectivity in Multi Level Heterogeneous Wireless Sensor Network

“…It works well with small and large scale networks and does not require prior distribution of sensor nodes. Inability to maintain stability and efficient use of remaining energy in multilevel environment is the main limitation of SEP. DB-SEP [8] , a modified version of SEP , proposed by Said Benkirane et al is 2 level energy based heterogeneous routing protocol. Objective of this protocol is to increase the lifetime of heterogeneous wireless sensor network by selecting cluster heads on the basis of initial energy, distance between nodes and distance with respect to base station.…”

“…where all sensor nodes have same initial energy are example of homogeneous clustering scheme.SEP [7], DB-SEP [8], DEEC [9], etc. are example of heterogeneous clustering scheme.…”
