Abstract:

Wireless sensor networks have characteristics that can send and receive information in different terrain conditions. Power supply for sensor nodes in different conditions, can be performed by different types of sources, such as battery power, batteries, solar cells, power alternating current rectifiers,... The issue of network routing, connection information between nodes and hub for such networks need coordination between resources, ensuring reliability and extending the lifetime of the network is essential. This paper gives a routing solution, taking into account the characteristics of the energy supply network nodes. By calculating the cost function depends gap between the nodes, energy supply-slope and energy generation capacity at the root node, routing protocol selects the optimal path according to the lowest cost function for data transmission. Combining the determination of the energy reserve on each node and cost function, routing solution will ensure optimal routing according to energy awareness, and appropriate to the network with network nodes are provided with the different energy supply types of sources.
