Wireless sensor network (WSN) is composed of several sensor nodes capable of communicating wirelessly to a centralized base station. These sensor nodes can be either static or dynamic based on the type of application in use. Data packets can be collected periodically or based on the occurrence of the monitored events, to which sensor nodes respond by transmitting the measured parameters to the base station for analysis purposes. The researchers in the field are currently focusing on finding a tradeoff balance between the energy consumption, packet delivery latency and the packet reception rate in an environment where sensors are statically deployed. However, the mobility issue has to be taken into account to overcome additional challenges that are mostly inherited by ad-hoc networks. In this paper, we put much emphasis on leach protocol categorized as a cluster-based routing protocol to improve its performance under the criteria of high mobility. The results prove the efficiency of the proposed leach-d protocol as it minimizes the overall energy consumption and packet delivery latency whilst it maintains a considerable packet reception rate.

Many routing protocols have been conceived to resolve the mobility issue in mobile wireless sensor networks. The cluster-based routing protocols is considered as a subtype category of routing protocols which represents a basic design to develop routing protocols destined to overcome WSN challenges with the existence of the mobility constraint. In this paper, we presented an improved version of the Leach protocol to mitigate the effect of mobility on communication between sensor nodes based on an estimated round period for cluster formation. The three following metrics were considered: the packet delivery ratio, the end-to-end delay, and the energy consumption. The results showed that the proposed improved version gives good results compared with leach protocol in a dimension equals to 404010 m. The overall performance proves that the proposed algorithm minimizes the overall energy consumption and packet delivery latency whilst it maintains a considerable packet reception rate. As future work, we will be focusing on conceiving a new synchronization schema to mitigate collisions between sensor nodes within the same cluster. The schema has to take into account the mobility constraint and propose a flexible synchronization time while maintaining optimal network performance.
