Seamless WSN Connectivity Using Diverse Wireless Links (original) (raw)

2017

Abstract

Data transfer using wireless sensor networks (WSN) is bound by its limited coverage range. In order to communicate data beyond the coverage capability of a WSN link and make it pervasive, the authors here propose a method of information handover using heterogeneous wireless links for sensor-based data transmission. They draw on connectivity, one of the main features of a pervasive network. In the handover method proposed here, the WSN link is part of a wireless module which integrates various heterogeneous wireless links. All these wireless links are combined and coordinated using media independent handover functions (MIH) in accordance with the 802.21 Standard. As wireless modules have multiple wireless links, each module can communicate with the others using any one of the active links. When these wireless modules consisting of multiple links move beyond the communication range of the WSN link to maintain continuous connectivity the MIH in the module triggers the other wireless li...
