dc.description.abstractMobile sensor networks are characterized by dynamic changes in communication links and network topology caused mainly due to node mobility. In such networks, it is a challenge to build a communication system that lasts longer and requires less reconfiguration and less communication overhead. In this paper, we propose an on-demand topology reconfiguration approach for mobile sensor networks aimed at enhancing the connectivity and performance. The proposed strategy groups nodes, elects cluster-heads, and, finally, selects gateways for inter-cluster communication. Neural networks are used to form clusters. Cluster-heads are elected based on the concept of minimum dominant set and the gateways are selected based on a willingness function. We demonstrate through simulations that the proposed strategy results in a well connected network.en_US
