In this paper, we propose a novel range-free localization algorithm tailored for mobile ad hoc networks (MANET)s. In contrast to most existing range-free techniques, we take into account the nodes mobility and hence enable the nodes to estimate their positions using solely their locally-available information, thereby avoiding any unnecessary costs in overhead and power that would have been incurred...
In this paper, we propose a novel range-free localization algorithm tailored for heterogeneous wireless sensor networks (WSNs), where nodes have different transmission capabilities. Two different approaches are developed to accurately derive the expected hop progress (EHP). It is shown that the obtained EHP depends solely on the information locally available at each node and, hence, can be computed...
In this paper, we propose a novel range-free localization algorithm able to reduce errors due to mapping the hops into distance units. Using the proposed algorithm, the mean hop size h̄s is locally derived at each regular or position-unaware node, thereby avoiding its broadcast by anchors (i.e., a few nodes aware of their exact position) as usually required in current state-of-the-art solutions and,...
In this work, we propose a novel hop-count based localization algorithm able to reduce errors due to mapping the hops into distance units. Using the proposed algorithm, the mean hop size ¯hs is locally derived at each regular or position-unaware node, thereby avoiding its broadcast by anchors (i.e., a few nodes aware of their exact position) as usually required in current state-of-the-art solutions...
