Paper Title
Energy Aware Localization In Wireles Sensor Network Using LUSA
Abstract
The technique of finding physical co-ordinates of a node is known as localization Importance of localization
arises from the need to tag the sensed data and associate events with their location of occurrence. Location information of a
sensor node can be obtained by using GPS. But, installing GPS in every node is not a feasible solution. This is because:
(i)sensor nodes are deployed in a very large number. Installing GPS at every node will increase the cost as well as size, (ii)
GPS consume power, which will effect the network lifetime. Moreover, location cannot be pre-programmed as it is unknown
where nodes will be deployed during their operational phase.In this thesis, we have made an attempt to address
localization in static sensor networks. For static network we have proposed distributed range based localization techniques
called (i) Localization using a single anchor node (LUSA),this technique is proposed for grid environment. In LUSA, we
have identified three types of node: anchor, special an unknown node. For every anchor node there exists two special node
and they are placed perpendicular to the anchor node. Localization in LUSA is achieved by a single anchor node and two
special nodes. Localization occurs in two steps. First special nodes are localized and then the unknown nodes. We have
compared LUSA with a closely related localization technique called Multi-duolateration(MDL). It is observed that the
localization error and localization time is lesser in LUSA. This not only reduces the localization time but also the
dependency.
Key words- Multi-Duolatertion(MDL), LUSA, beacon node ,Settled node.
