Due to the geographical correlation of the sensed data, location information is commonly used to name the gathered data and address nodes and regions in data dissemination protocols. In general, to estimate its location, a node needs the position information of, at least, three reference points (neighbors that know their positions). In this work, we propose a different scheme in which only two reference points are required to estimate a position. To choose between the two possible solutions of an estimate, we use the known direction of the recursion. This approach leads to a recursive localization system that works with low density networks (increasing in 40% the number of nodes with estimates in some cases), reduces the position error in almost 30%, requires 37% less processor resources to estimate a position, uses less beacon nodes, and also indicates the node position error based on its distance to the recursion origin. No GPS-enabled node is required, as the recursion origin can be used as the relative coordinate system.","PeriodicalId":379037,"journal":{"name":"Proceedings. 14th International Conference on Computer Communications and Networks, 2005.

In this paper, we study the modeling and analysis of search-based physical attacks in sensor networks. We define a search-based physical attack model, where the attacker walks through the sensor network using signal detecting equipment to locate active sensors, and then destroys them. We consider both flat and hierarchical sensor networks. The attacker in our model uses a weighted random selection based approach to discriminate multiple target choices (normal sensors and cluster-heads) to enhance sensor network performance degradation. Our performance metric in this paper is accumulative coverage (AC), which effectively captures coverage and lifetime of the sensor network. We then conduct detailed evaluations on the impacts of search-based physic attacks on sensor network performance. Our performance data clearly show that search-based physical attacks significantly reduce sensor network performance. We observe that attack related parameters, namely attacker movement speed, detection range and accuracy have significant impacts on the attack effectiveness. We also observe that the attack effectiveness is significantly impacted by sensor network parameters, namely the frequency of communication and frequency of cluster-head rotation. We believe that our work in this paper on modeling and analyzing search-based physical attacks is an important first step in understanding their overall impacts, and effectively defending against them in the future.","PeriodicalId":379037,"journal":{"name":"Proceedings. 14th International Conference on Computer Communications and Networks, 2005.
