TART: Traffic-Aware Routing Tree for Geographic Routing

2008 IEEE Wireless Communications and Networking Conference, 2008
Tree routing is one of the detouring strategies employed in geographic routing to help find a detour for a packet to leave a local minimum. The effectiveness of tree routing depends on the quality of the pre-constructed routing trees. Existing tree construction methods build trees in a top-down and centralized fashion and do not consider the traffic ...

Geographic routing in city scenarios

ACM SIGMOBILE Mobile Computing and Communications Review, 2005
Position-based routing, as it is used by protocols like Greedy Perimeter Stateless Routing (GPSR) [5], is very well suited for highly dynamic environments such as inter-vehicle communication on highways. However, it has been discussed that radio obstacles [4], as they are found in urban areas, have a significant negative impact on the performance of ...

HSecGR: Highly Secure Geographic Routing

Journal of Network and Computer Applications, 2017
Abstract An ad hoc wireless network is a set of nodes connected by wireless links in which nodes cooperate to forward packets from a source to a destination. Geographic routing (or position-based routing) has become an attractive solution for such networks since it reduces routing control overhead flooded in the network to construct routes (routes ...

Moving geographic routing to practice

2012 IEEE International Conference on Cyber Technology in Automation, Control, and Intelligent Systems (CYBER), 2012
Geographic routing algorithms are promising in wireless sensor network due to their scalability. However, research activities carried out in the last decade are still not able to implement geographic routing in realistic environments. Majority of geographic routing algorithms use face routing on a planar graph where the planarization relies on the ...

Locally Optimal Source Routing for energy-efficient geographic routing

Wireless Networks, 2007
We analyze the problem of finding an energy-efficient path from a source node to a destination using geographic routing. Existing schemes have neglected the fact that neighbors which are not closer to the destination than the current node can still reduce energy consumption by taking part in the selected path. Moreover, recent works have confirmed that

Multi-hop Dynamic Geographic Routing

1998
Geographic Routing is a new process for routing data packets through an internetwork of computers. Our process distinguishes itself from the current routing technology by using arbitrary geographical regions (denoted by longitude and latitude) instead of logical computer addresses as the criteria to route a packet. The purpose of this new technology is

Characterizing the Impact of Routing Holes on Geographic Routing

2005 Systems Communications (ICW'05, ICHSN'05, ICMCS'05, SENET'05), 2005
The performance of geographic routing protocols is largely determined by the routing holes from which they must recover. In this paper we examine routing hole characteristics. In simulations of large networks of varying size and placement strategy we investigate (1) the size of routing holes, (2) the number of hops needed to escape from a routing hole,

Geographic Routing Protocol and Simulation

2009 Second International Workshop on Computer Science and Engineering, 2009
The research in the reduction of routing flooding in Ad hoc routing protocol is a hot direction. The GRP Routing Protocol uses regional and hierarchical regional method to optimize flood. We build simulation model of GRP and OLSR by OPNET to make a comparison., The result of the simulation shows GRP Routing Protocol can effectively limit the flooding ...
