The term adhoc network refers to a network that is created spontaneously, self-powered and infrastructure less networks. The energy in adhoc network does a crucial role in lengthening the network life span. The energy saving techniques in adhoc networks help to overcome the problem of link breakage. adhoc networks are generally used for specific scenarios, such as Earth Quakes, Military, Wild Life Monitoring, under water surveillance monitoring and disaster management. In this type of scenario, adhoc network nodes are located normally far away from each other and each node is independent in network and individually powered by batteries. So, Battery is the major constraint of this type of adhoc network. In an adhoc network, communication between nodes is possible by one another through forwarding packets and finding the paths to the destination by itself. Path selection in an adhoc network keeps in consideration energy usage, to increase the duration of the network. The selection of the optimal path can increase the duration of the network, if the highest leftover energy parameter is used to choose a path and a path with less hop count, the possibility of increase in network lifetime is more. The path selection is performed using the adhoc routing protocols and the AODV protocol has already been proven by researchers that it is appropriate for use in an adhoc network to increase battery efficiency and to lengthen the network life span. But, the AODV protocol has many disadvantages while determining the optimal path due to the reason, such as AODV protocol always tends to choose the shortest path without calculating the intermediary node residual energy, and then this leads to link breakage in the path. To overcome this drawback of the AODV protocol, we have designed a newly modified protocol called the Optimized Residual Energy Selection Adhoc On Demand Distance Vector (ORES-AODV) protocol, which selects the optimal path by calculating the average of maximum residual energy and by finding the average energy overhead of the intermediate nodes in the path and the mobility of the nodes are compared using mobility models. This protocol is 7% efficient than the other protocols proposed by taking AODV as the base protocol. Another Adhoc Network, the Wireless Sensor Network, has seen tremendous research in several years to solve the energy dissipation problem. To address the issue of energy waste in Wireless Sensor Networks, a new protocol called Modified Mobile-sinks-based Energy-efficient Clustering Algorithm (M-MECA) is introduced, which is based on mobile sink and clustering. The proposed protocol is compared with other protocols and the protocol developed is 6% efficient as evaluated with other protocols.
