Wireless sensor networks are used in many mission-critical applications such as target tracking in battlefield, emergency alarm, disaster detection, etc. In such applications, QoS provisioning in time domain is indispensable. Moreover, due to the coexistence of many kinds of sensory data, QoS provisioning should support not only one, but multiple levels of end to end delay constraints. Due to several characteristics such as the limitations on energy supply, available storage and computational capacity of the sensor nodes, guaranteeing timely delivery in WSNs becomes a challenging problem. To overcome these limitations, several lightweight and stateless QoS-based geographic routing protocols have been proposed. The existing protocols work well in networks without routing holes (i.e. regions with no working sensors). However, with the occurrence of routing holes, they suffer from the so-called local minimum phenomenon and traffic congestion around the hole boundary. In this paper, we take into account the presence of routing holes and propose a delay guaranteed geographic routing protocol which can support multiple end to end delay levels. The main idea is to be aware early about the hole and then utilize this awareness in determining a routing path which can avoid the hole. The simulation result shows that our protocol can increase the packet delivery ratio up to more than 3.1 times in comparison with a well-known existing protocol. |
