摘要：A mobile ad hoc network (MANET) is a wireless communication network and the nodes that are not lies within the direct transmission range of each other depend on the intermediate nodes to forward data. Opportunistic data forwarding has drawn much attention in the research community of multi hop wireless networking, with most of the researches conducted for stationary wireless networks. Opportunistic data forwarding has not been widely utilized in mobile ad hoc networks (MANETs) and the main reason is the lack of an efficient lightweight proactive routing scheme with strong source routing capability. So, in the existing method, a lightweight proactive source routing (PSR) protocol is used. PSR can maintain more network topology information than distance vector (DV) routing to facilitate source routing, although it has much smaller overhead than routing protocols. But the disadvantage of this method is network overwhelming due to the route update. Furthermore, due to mobility of the nodes more energy is consumed. So in the proposed system an innovative technique is introduced which is called delay and energyaware routing (DEAR) for reducing energy consumption and reduce the overhead. In this technique the delay is selected until the end of the cycle so that only one update is broadcast in each period. Furthermore, due to the dynamic topology, node consumes more energy while roaming. The topology control approach has been introduced to reduce the energy consumption of nodes. In topology control approach, two cases are considered, i) Energy consumption of the node and routes. ii) Link stability and location stability. An experimental result shows that when compared to the existing method there is less energy consumption and high network lifetime in the proposed system.
