An Efficient Location Server for an Ad Hoc Network*

چکیده
Previous research has illustrated that locationbased routing protocols improve the effectiveness of mobile ad hoc network (MANET) routing. The goal of a location server, which may be used in conjunction with a locationbased routing protocol, is to provide accurate location information on the mobile nodes in the network. In this paper, we implement a location server for a MANET using our Legend Exchange and Augmentation Protocol (LEAP). We use LEAP to provide a Network Environment Wireless State (NEWS) service. The goal of NEWS is to collect and distribute “news” (such as location information) on the mobile nodes. We compare our legend-based NEWS service to three other location service alternatives via extensive simulations, and illustrate that our LEAP implementation offers both higher accuracy and lower overhead.

Improving Quality of Service Routing in Mobile Ad Hoc Networks Using OLSR
Mobile ad hoc networks (MANET) are constructed by mobile nodes without access point. Since MANET has certain constraints, including power shortages, an unstable wireless environment and node mobility, more power-efficient and reliable routing protocols are needed. The OLSR protocol is an optimization of the classical link state algorithm. OLSR introduces an interesting concept, the multipoint r...

Bluetooth Location Network (BLN) is a Bluetooth radio network that is composed of some mobile Bluetooth devices and static Bluetooth units, and is established at the system initialization to form a spontaneous network topology. In a BLN, a multicast service is defined as the periodical delivering of messages from a Service Server to a set of mobile devices which are the multicast members predef...
متن کاملBroadcast Routing in Wireless Ad-Hoc Networks: A Particle Swarm optimization Approach
While routing in multi-hop packet radio networks (static Ad-hoc wireless networks), it is crucial to minimize power consumption since nodes are powered by batteries of limited capacity and it is expensive to recharge the device. This paper studies the problem of broadcast routing in radio networks. Given a network with an identified source node, any broadcast routing is considered as a directed...

Location aware computing is popularized and location information has more important before. Ubiquitous computing also needs locaiton information. In this paper we propose location estimation system using multi-hop wireless ad-hoc network. The proposed system estimates locations of mobile hosts, using distance between hosts and the locations of some special hosts which know each location by GPS ...
