The wireless link can be unreliable in realistic wireless sensor networks (WSNs). Energy efficientand reliable data forwarding is important because each node has limited resources. Therefore, we mustsuggest an optimal solution that considers using the information of the node’s characteristic A wirelesssensor network is composed of a large number of low-cost devices distributed over a geographic area. Sensornodes have limited processing capabilities therefore simplified protocol architecture should be designed so asto make communications simple and efficient. Moreover, the power supply unit is based on an energy-limitedbattery the networks should be aimed at minimizing the energy consumption. A forwarding scheme for WSNaimed at combining low computational complexity and high performance in terms of energy efficiency andreliability. The approach relies on a packet-splitting algorithm based on the BURST algorithm. Theperformance of burst is to be obtained by Shortest Path with Load Balancing (SP).The energy efficiency islow in this splitting process compare to those shortest paths. To estimation of the mean energy reductionfactor achievable with the forwarding scheme should be derived and the reassembling is done in destinationside, the values to be coded in code block and simulated using MATLAB simulator. The proposed algorithmoutperforms in terms of energy saving and increases the network lifetime.
