Distributed Cooperative Control Algorithm for Topology Control and Channel Allocation in Multi-radio Multi-channel Wireless Sensor Network: From a Game Perspective

摘要: With the development of wireless communication technology, spectrum resource is becoming more and scarce, which results in increase network co-interference then incurs data retransmission probability. Hence, single channel based algorithms are facing a myriad challenges. Moreover, reducing energy consumption prolonging lifetime key issue for sensor network. In order to alleviate interference while balancing consumption, we tend design multi-radio multi-channel algorithm that joint topology control allocation. Firstly, study interactions between allocation, lay basis further reduction transmission power interference. We take account radio power, node residual construct cooperative game model This has proven guarantee existence Nash equilibrium. And on this model, distributed Cooperative Control Algorithm Topology Channel allocation (CCATC) developed, can converge Equilibrium preserve connectivity. Furthermore, simulation demonstrate CCATC not only greatly reduce but also prolong by nodes. The comes with improvement throughput. Besides, many other attractive features such as higher utilization, better robustness, fairer less end-to-end delay.
