PSGR: priority-based stateless geo-routing in wireless sensor networks

Yingqi Xu, Wang-Chien Lee, Jianliang Xu, G. Mitchell
IEEE International Conference on Mobile Adhoc and Sensor Systems Conference, 2005.  
In this paper, we propose a priority-based stateless geo-routing (PSGR) protocol to address these issues.  ...  Based on PSGR, sensor nodes are able to locally determine their priority to serve as the next relay node using dynamically estimated network density.  ...  INTRODUCTION Geo-routing protocols have been widely adopted in the design of wireless sensor networks [12] , [14] .  ...

Energy-Aware and Time-Critical Geo-Routing in Wireless Sensor Networks

Yingqi Xu, Wang-Chien Lee, Jianliang Xu, Gail Mitchell
2008 International Journal of Distributed Sensor Networks  
In this paper, we propose a priority-based stateless geo-routing (PSGR) protocol that addresses these issues.  ...  A novel protocol, called priority-based stateless geo-routing (PSGR), is proposed to achieve the following design objectives: Stateless architecture.  ...  Summary In this paper, we presented a novel and robust stateless geo-routing protocol, namely, PSGR, for large-scale location-aware wireless sensor networks.  ...

A Distributed Geo-Routing Algorithm for Wireless Sensor Networks

Gyanendra Prasad Joshi, Sung Won Kim
2009 Sensors  
Geographic wireless sensor networks use position information for greedy routing. Greedy routing works well in dense networks, whereas in sparse networks it may fail and require a recovery algorithm.  ...  However, these algorithms are generally costly for resource constrained position-based wireless sensor networks (WSNs).  ...  [17] , and bypass in Priority-based Stateless Geo-Routing (PSGR) [18] .  ...
