Mobility Support for the Routing Protocol in Low Power and Lossy Networks
Mobility is the most issues for the majority of protocols including the RPL (IPv6 Routing Protocol for Low Power and Lossy Networks) RPL a routing protocol standardized by IETF is usually used in Internet of Things Technology. It is proposed to support communications in Low power and Lossy Networks (LLNs) However, mobility limits the use of RPL protocol in realistic study. In this paper we have classify the mobility models in two entities in order to evaluate the performances of RPL in each entity separately. So we have defines two different scenarios. We first, evaluate characteristics of RPL with a group mobility models which contain Reference Point Mobility Model (RPGM) and Nomadic Mobility Model (Nomadic) Mobility Models. Then we give another evaluation of features of RPL with the Entity mobility models which contain Random Walk Mobility Model(RWK) Random Waypoint Mobility Models (RWP) and self similar least action walk (SLAW) Mobility models. The results show that the type of mobility models has a direct influence on the protocol performances. In addition, increasing of number of nodes causes an increasing of all parameters, especially in delivered and received data. Furthermore, the group mobility models give better metrics than entity mobility models in terms of lost packets, Packet Delivery Ratio (PDR) and Throughput. Also, in each type of mobility models each model provides better metrics than others. RPG offers best number of lost packets and PDR than Nomadic model and lowest in terms of Throughput while SLAW models gives the best value in all metrics than RWK and RWP. Our simulation shows clearly that lost packets, PDR and Throughput are directly related to the type of mobility models.
