A survey on mobility management protocols in Wireless Sensor Networks based on 6LoWPAN technology

Mobility has the advantage of enlarging the WSN applications of the Internet of Things. However, proposing a mobility support protocol in Wireless Sensor Networks (WSNs) represents a significant challenge. In this paper, we proposed a survey on mobility management protocols in WSNs based on 6LoWPAN technology. This technology enables to connect IP sensor devices to other IP networks without any need for gateways. We highlighted the advantages and drawbacks with performances issues of each studied solution. Then, in order to select a typical classification of mobility management protocols in WSNs, we provided some classification criteria and approaches on which these protocols are based. Finally, we presented a comparative study of the existing protocols in terms of the required performances for this network type. (C) 2014 Elsevier B.V. All rights reserved.
