摘要
A typical wireless sensor network is conceived as bring a very large collection of low-powered, homogeneous nodes that remain stativ post-deployment and forward sensed data to a single sink via multi-hop communication. During the recent years, many energy-efficient load balancing protocols have been proposed for wireless sensor networks. Because a wireless networks consists of a large number of nodes with limited resources, the load balancing protocol is one of the key issues which can be solve the tradeoff between the service capacity and energy efficience. Load balancing protocols typically employ only a network capacity oriented approach in the next hop node is selected on adjacent or network information. This approach draw into a large overhead when the accurate adjacent information is needed for efficient and reliable routing. When an application service is caused large interaction between the adjacent nodes, the previous load balancing protocols without considering this issue were re-allocated the adjacent nodes and the other adjacent is re-allocated another region. This is not efficient for network performance because the previous protocols are generated the large overhead by increased routing and overhead. So, we propose a user-oriented load balancing scheme for an energy-efficient load balancing in wireless networks which is based on allocate load on wireless sensor nodes proportionally to each of the agent's capacity and user-oriented approach. This proposed scheme is combined dynamic provisioning algorithm based on greedy graph and user oriented load balancing scheme for maintain of the performance and stability of distributed system in wireless sensor networks. We address the key functions for our proposed scheme and simulate the efficiency of our proposed scheme using mathematical analyze.
