Multi radio clustering protocol for mobile networks

Communication and data networking field are being changed by the use of wireless networks, which enables user to communicate and access application and information without wires anywhere and anytime. This emerging and innovative technology while used in the computer networks which are supporting more flexibility and mobility. But one of the most considerable factors is power consumption. Because majority of nodes while using single radio platform (WLAN) in Wi-Fi area, power consumption becomes larger. So we propose a novel distributed clustering approach for energy saving using (LPR) and (HPR) within a single platform and this approach is based on clustering the nodes within the Wi-Fi area. By selecting a CHCs and GWNs among the member nodes, we have considered nodes highest residual energy level, signal strength and topology features. Cluster head coordinators (CHCs) to control the member nodes within the cluster. Here the cluster heads are act as a Coordinator between WLAN and PAN, and these cluster heads are responsible to make transmission process and forwarding data packets via the secondary radio interface (PAN) with their member nodes and the Gateway nodes (GWNs) are used to bridge the clusters to avoid the cluster head failures. Communication between the neighboring clusters on behalf of their cluster heads, Gateway nodes are used. So the clusters are independently controlled and dynamically reconfigured the nodes. Based on this, we presenting a Multi-Radio clustering protocol (MRCP) using Ns2, which effectively reforms the clusters and prolong the network lifetime, according to the user´s application, power and bandwidth.
