A connectivity protocol for star topology using wireless sensor network

In this work, we concentrate on network which is not able communicate with the sensors due to fail in the sensing process due to the temporary links of clutter with the access point. The novelty of the work is mainly divided into two folds mainly i)to know the connectivity problems and its requirements in the relay networks, ii) to restore the connection problems on the sensor nodes and to recover the loss of information occurred in the connectivity obstructions. we propose the LAL protocol which automatically senses the failure location of the sensor nodes and backs up with the backup sensor node in a ad-hoc mobile environment. In this paper, mainly we concentrate on the existing protocol neighbor-assisted connectivity recovery protocol (NACRP), and the LAL protocol adding the backup sensors for both the protocols and comparing the different parameters for the better performance.
