Design and implementation of grid-based hybrid network for energy efficient wireless sensor networks

The Wireless Sensor Networks (WSNs) are consisting of many tiny devices called (sensor nodes) which are distributed spatially in a network, such devices have the ability to sense, process, as well as to communicate. And cooperates with each other to complete specific tasks. Since these nodes have limited energy supplies due to its battery-based nature, a clustering technique is particularly used to overcome the problem of energy consumption in addition to its impact on the network's lifetime. Grid-Based Hybrid Network Development technique has been provided in this study, such method enabled enhancing the conservation of energy as well as extending the lifetime of networks in the WSNs. By using Matlab tool, this technique showed the throughput that is related to the residual energy as well as the consumed energy for (500, 600) sensor nodes in a specific number of iteration processes (1500 rounds). As a result, we got the optimal solution of how many sensor nodes were kept alive, what was the percentage of dead nodes through that number of rounds, maximum number of rounds resulting in improving the lifetime of network, and overall consumed energy in two energy initial cases (Eini = 1 Joule, Eini = 2 Joules) for our proposed (8 x 8) and (10x10) grid size network.
