The occurrence of multiple holes in wireless sensor networks poses many challenges in designing routing protocols. The traditional scheme is forwarding packets along the hole perimeters. However, this scheme leads to two serious problems: data concentration around the hole boundaries and routing path enlargement Recently, several approaches have been proposed to address these two problems, wherein...
Wireless sensor networks (WSNs) are used in many mission-critical applications, such as target tracking on a battlefield, emergency alarms, and disaster detection. In such applications, QoS provisioning in the timeliness domain is indispensable. Moreover, because of the diversity of sensory data, QoS provisioning should support not only one but multiple levels of end-to-end delay constraints. As a...
