This paper studies task allocation in cluster-based Wireless Sensor Network (WSN) using negotiation model. We study both the negotiation reasoning model and the negotiation protocol for task allocation to achieve energy efficiency while balancing nodes energy. Reasoning model determines the offer generate scheme and gives control over negotiation process. A time depending Boulware function is used...
Given the resource-constrained and distributed nature of Wireless Sensor Network (WSN), collaboration is very necessary for task execution. However traditional collaborative methods can not be applied to WSN directly. In this paper, we focus on coalition-based method of multi-nodes collaboration (CMMC) which is performed to achieve a maximum utility through collaboration while minimizing the communication...
Mobility Model for mobile users is an important part of simulation of the wireless mobile network's resource management and optimization. The Manhattan Mobility Model proposed by ETSI is highly versatile. However, its random direction selecting strategy lacks of objectives, which means the scene of hotspot attracting user mobility could not be simulated accurately. In order to simulate the user mobility...
Wireless Sensor Network (WSN) is fault-prone given the resource-constrained characteristic of sensors and harsh deployment environment. Failure of sensors may cause negative consequences on the considered applications. Therefore, WSN should be able to tolerate the failures of sensors and self-recover from fault to guarantee the service. However current studies mostly focus on fault diagnosis, and...
