Comparing The Benefits of Controlled Sink Mobility with Random, Predictable and Geographic Mobility in Wireless Sensor Networks

Todays, the use of high speed network communications as well as power, simplicity and low cost have been presented as a new approach in many scientific researches.Wireless sensor networks consist of a large number of low-cost and small size sensor nodes, which can be embedded in environments in order to accomplish a specific mission by measuring specific parameters such as pressure or temperature. In Recent research, sink mobility in wireless sensor networks can be divided into two main categories: static and dynamic sink movement whereas the speed of the network can be controlled or random or predictable or geographic. In this article, we discuss these methods and do count the advantages and disadvantages of each methods.The rest of this paper is organized as follows. In section1 discuss about wireless sensor networks and its limitations and the importance of mobility models. After that, mobility models are reviewed and classified in section 2. Also, a discussion regarding the studied mobility models is presented. Finally, the paper is concluded in the last section.
