Abstract :
Localization by connectivity in wireless sensor networks is an approach that does not impose any additional hardware to sensor nodes and it only uses connectivity information. In this approach localization is erroneous. In this paper we propose a formula to estimate average of error in localization of random sensor network. The work is started with a view on localization in regular distributed network. Obtained formula will be generalized for randomly distributed network using the random density function of connectivity. Proposed formula shows that the error rate is different depending on the network parameters. Simulation results confirm the performance and correctness of the formula.
