“…In mobility-aware WSNs, many existing solutions require mobile nodes to constantly evaluate link quality, based on the Received Signal Strength Indicator (RSSI) of acknowledgments received from its temporary next-hop (e.g.,MA-MAC [12] , MX-MAC [3] , MARI-MAC [13] ). Hence, if the mobile node evaluates a too low quality of the link between its current next-hop and itself (i.e., persisting deterioration in the link quality), it initiates a neighborhood discovery process which may lead to a handover situation.…”

In Wireless Sensor Networks (WSNs) the nodes can be either static or mobile depending on the requirements of each application. During the design of Medium Access Control (MAC) protocols, mobility may pose many communication challenges. These difficulties require first a link establishment between mobile and static nodes, and then an energy efficient and low delay burst handling mechanism. In this study, we investigate preamble-sampling solutions that allow asynchronous operation. We first introduce anycast transmission to ContikiMAC where a mobile node emits an anycast data packet whose first acknowledging node will serve as responsible to forward it towards the sink. Once this link is established, burst transmission can start, according to the respective burst handling mechanism of ContikiMAC. Although it is considered as negligible in the literature, such an anycast-based on-the-fly operation Georgios Z. Papadopoulos actually results in high packet duplication at the sink. Hence, we demonstrate that even a basic anycast-based MContikiMAC would fail to handle bursty traffic from mobile nodes mainly due to increased unnecessary traffic and channel occupancy. We then propose Mobility-Enhanced ContikiMAC (ME-ContikiMAC), a protocol that reduces packet duplications in the network by more than 90 % comparing to M-ContikiMAC. Moreover, our results in a 48-node scenario show that ME-ContikiMAC outperforms a number of state-of-the-art solutions (including MoX-MAC and MOBINET), by terms of reducing both delay and energy consumption.

“…Besides MAC and routing protocols holding incoming and outgoing nodes, they should also offer a technique in order to provide a continuous end-to-end communication link. [5] The protocols need to be selected in such a way that they function effectively in both stationary and mobile conditions. It must be conscious about mobility and adaptable to speed of mobile sensors.…”

“…By analyzing previous papers [5], [7] related to mobility aware MAC protocol, it was found that the relay nodes are selected randomly. But there may be a situation that randomly selected relay node may be overloaded or it can be moving, leading to data loss and repeated retransmissions.…”

In mobile environment of wireless sensor networks (WSN), the fixed frame of MAC protocol causes performance degradation such as packet collision due to overloading etc. In this paper an optimal load and mobility aware MAC protocol for WSN is proposed. Each node measures the received signal strength (RSS) from the receiver by monitoring the acknowledgement packets and based on the RSS value, the link quality and mobility of the node can be predicted. Depending on the predicted link quality and mobility, the relay node selection process is initiated. In relay node selection process the neighbors with minimum load and good RSSI values is selected as the relay node. The moving source then transmits the packets through this relay node. This protocol reduces the packet drop due to overload and weak link quality. By simulation results, it is shown that the proposed approach minimizes the energy consumption.
