Mobility support for the routing protocol in low power and lossy networks

Mobility is the most issues for the majority ofprotocols including the RPL (IPv6 Routing Protocol for LowPower and Lossy Networks). RPL a routing protocolstandardized by IETF is usually used in Internet of ThingsTechnology. It is proposed to support communications in Lowpower and Lossy Networks (LLNs). However, mobility limitsthe use of RPL protocol in realistic study. In this paper wehave classify the mobility models in two entities in order toevaluate the performances of RPL in each entity separately. Sowe have defines two different scenarios. We first, evaluatecharacteristics of RPL with a group mobility models whichcontain Reference Point Mobility Model (RPGM) and Nomadic Mobility Model (Nomadic) Mobility Models. Then wegive another evaluation of features of RPL with the Entitymobility models which contain Random Walk Mobility Model(RWK), Random Waypoint Mobility Models (RWP) and selfsimilarleast action walk (SLAW) Mobility models. The resultsshow that the type of mobility models has a direct influence onthe protocol performances. In addition, increasing of numberof nodes causes an increasing of all parameters, especially indelivered and received data. Furthermore, the group mobilitymodels give better metrics than entity mobility models in termsof lost packets, Packet Delivery Ratio (PDR) and Throughput. Also, in each type of mobility models each model providesbetter metrics than others. RPG offers best number of lostpackets and PDR than Nomadic model and lowest in terms ofThroughput while SLAW models gives the best value in allmetrics than RWK and RWP. Our simulation shows clearlythat lost packets, PDR and Throughput are directly related tothe type of mobility models.
