Managing mobile node mobility in target tracking applications in mobile sensor networks is addressed in [17].
To schedule the handover process efficiently, the RMPA strategy makes use of a context aware handover policy; that is, a handover policy based on the mobile node mobility pattern, the time required to perform the handover, the neighboring network conditions, the data traffic profile, the received power signal, and current location and speed information of the train.
where 'd' and 'k' denote the average distance of communication between mobile nodes and mobility proportion variable, respectively.
We have selected a simplified LOS propagation model for mobile nodes, and the nodes mobility has been neglected by the assumption of a static network topology.
Social beings such as humans may act as a carrier of mobile nodes, and therefore mobility pattern of node follows a social-based movement model.
With recent advances in deploying sensor nodes mounted on mobile platforms, node mobility is becoming an attractive alternative to improve network coverage dynamically in sensor networks.
In the following figures, we assume that mobile nodes perform sequential node mobility management as discussed in Sections 4.4 and 5.4, since it can be seen that the performance with mobility algorithm based on sequential approach is much closer to that with evaluated based on forward dynamic programming algorithm (see Figure 10 for comparison).
The IETF has standardized the host-based Mobile IPv6 (MIPv6) [7] and Network Mobility (NEMO) [8] protocols to address the management needs of the global mobility of mobile nodes (MNs) and mobile networks, respectively.
The introduced hybrid routing protocol by Peppas considers heterogeneous mobility for mobile nodes [42].
Due to the mobility of mobile nodes, the topology of a MANET frequently changes and thus results in the disability of originally on-the-fly data transmission routes.
