Exact Localization on Resource Limited Sensor Nodes - Making it Feasible -
نویسندگان
چکیده
The random deployment process and the unpredictable movement of sensor nodes lead to a high demand for an exact and reliable self localization process. Existent methods are mostly not feasible on strongly resource limited sensor nodes with an absolute minimum of energy. Thus, this paper describes the "Distributed Least Squares (DLS)"-algorithm that reduces the needed amount of energy to a minimum by distributing the complex localization process. DLS is a resourceaware localization method that achieves 47% computation savings and 86% energy savings compared to the reference method, a "Fully Distributed Multilateration" on every sensor node. In the end, DLS significantly extends the overall

A multi-hop PSO based localization algorithm for wireless sensor networks
A sensor network consists of a large number of sensor nodes that are distributed in a large geographic environment to collect data. Localization is one of the key issues in wireless sensor network researches because it is important to determine the location of an event. On the other side, finding the location of a wireless sensor node by the Global Positioning System (GPS) is not appropriate du...

متن کاملRandom Key Pre-Distribution Techniques against Sybil Attacks
Sybil attacks pose a serious threat for Wireless Sensor Networks (WSN) security. They can create problems in routing, voting schemes, decision making, distributed storage and sensor re-programming. In a Sybil attack, the attacker masquerades as multiple sensor identities that are actually controlled by one or a few existing attacker nodes. Sybil identities are fabricated out of stolen keys, obt...
