Abstract
It is well-known that in wireless sensor networks using minimum-energy
paths to transfer data from sensor nodes to base station is not an
energy-balancing option and not the optimal solution if lifetime,
defined as the duration till the first node in the network exhausts all
its energy, is of concern. However, the net effect of minimum-energy
routing on network lifetime has not been studied in detail before. In
this study, we present comparative analysis using both simulations and
linear programmming models to investigate this issue with respect to
various system parameters such as energy model, network area and number
of nodes. Our results show that network lifetime achieved with
minimum-energy routing could be as low as 19.3\% of the maximum
achievable lifetime depending on the values of other system parameters.... Show more Show less
