Energy limitation is one of the most critical challenges in the area of sensor networks. Sleep scheduling mechanisms can reduce the energy consumption. Coverage mechanisms attempt to cover the area with the minimum possible number of sensors. There are many area coverage approaches which also consider the connectivity problem. However, in the area of point coverage, there are limited mechanisms that...
We present a new scheme to reduce the end-to-end routing delay in the mission-critical applications of the wireless sensor networks (WSNs) under the duty cycle model. While greedy routing in the synchronized MAC model has been studied extensively, efficient routing in an asynchronous MAC model is considerably different because the wake-up time and availability of a node along the pre-decided path...
In this paper, we explore a quantitative approach to accountable wireless multi-hop networks. We propose using hierarchical P-Accountability to adapt the requirements of modeling a complex network environment and assess the degree of accountability in a fine-grained manner. We have defined P-Accountability and demonstrated its use in the hierarchical network environment. In addition, we apply P-Accountability...
