Extended diffused key-information based routing protocol in ad hoc networks

In this paper we investigate the search path when building a wireless mesh network under extended ad-hoc network, and we propose a search method that can reduce power consumption. The route search part and the node part - which can be a mobile PC or a mobile phone, etc. -are combined in the proposed method. Moreover, we aim at improving the efficiency of the communication between nodes under the extended wireless mesh network. This is achieved by making the nodes aware of the location of each other. The proposed method provides several advantages: First of all, useless route searches are reduced by flooding using the location information between nodes. Second, we are able to construct shortest routing paths, avoid the communication with AP to pass the location information of each node, and reduce the power consumption of the nodes.
