Routing for ad-hoc wireless network is challenging, many routing strategies have been proposed in literature. With the availability of affordable Global Position System equipped devices, location-aware routing provides a promising foundation for developing an efficient and practical solution for routing in ad-hoc wireless network. Current geographic forwarding strategies and geographic routing ...

Geographic routing for wireless sensor networks requires a source that can encapsulate the location of a sink in each data packet. How a source can obtain the location of a sink with low overhead is a difficult issue. This letter proposes a Quorum Based Sink Location Service (QSLS) which can be exploited by most geographic routing protocols in arbitrary irregular wireless sensor networks. key w...

Geographic routing has become a popular routing protocol in mobile ad hoc networks (MANETs) because of its simplicity and low overhead. Recent research has recognized the applicability of geographic routing in vehicular mobile ad hoc networks (VANETs) without considering much the particular constraints in such an environment. Characteristics unique to VANETs are rapidly and dynamically changing...

Over the past decade, energy efficiency has consistently been a critical research topic in the field of wireless sensor networks. In wireless networks, signal interference often leads to power waste in a sensor node. Several SINR-based routing algorithms designed for energy efficiency or interference avoidance had been proposed. However, they are either too complex to be useful in practices or ...

In this paper, we propose a novel routing algebra system to investigate greedy routing in geographic routing. Four important algebraic properties, respectively named mutex, transition, source independence and strict preference, are defined in this algebra system. Based on these algebraic properties, the necessary and sufficient conditions for the loop-free and consistent compatibilities of gree...

In this paper, we study the geographic properties of Internet routing. Our work is distinguished from previous studies of Internet routing in that we consider the geographic path traversed by packets, not just the network path. We examine several geographic properties including how circuitous Internet routes tend to be, how multiple ISPs along an endto-end path share the burden of routing packe...

We present geographical secure path routing, an infrastructure free geographic routing protocol, that is resilient to disruptions caused by malicious or faulty nodes. Geographic locations of anonymous nodes are authenticated in order to provide location authentication and location privacy simultaneously. Our protocol also authenticates the routing paths taken by individual messages. This provid...

Minimizing Energy consumption is considered as one of the most important principles in the development of routing protocols for Wireless Sensor Networks (WSN). In this study, we propose a Location based Energy-Aware Reliable routing protocol (LEAR) for WSN based on sensor position and clustering. Geographical routing protocols are efficient and convenient for optimum energy consumption and band...

Due to the utilization of location information, geographic ad hoc routing presents superiority in scalability compared with traditional topology-based routing in mobile ad hoc networks. However, the consequent solicitation for location presence incurs severe concerns of location privacy, which has not been properly studied. In this paper, we attempt to preserve location privacy based on the ide...
