Mobile Wireless Sensor Network: Routing Protocols Overview

Wireless sensor Networks (WSNs) became in one of the important technologies in our days in which it is applied in many applications and domains. Further, most of these applications are under the umbrella of the Internet of things (IoT) and that required a particular Quality of Service (QoS). Recently, many vital applications need mobility, which Mobile WSNs (MWSN) subscribes in these needs. However, the low-cost technology of the MWSNs is the first obstacle to improve performance in these applications. The usual methods of routing algorithm cannot be applied in MWSNs. In addition, security has become a primary concern to provide secure communication between wireless nodes, with additional challenges related to the node’s computational resources. Particularly, the wireless ad-hoc communication adopted by the sensor nodes communication makes WSNs more susceptible to different types of security threats and attacks. In this paper, we present the specification of MWSN, and based on that we describe the different routing protocols used. Second, we discuss the performance of these protocols and propose a new technique to improve MWSN performance.
