ABSTRACT Analysis of scalability for AODV routing protocol in wireless sensor networks

In the recent years, wireless sensor networks have become the one of the top area of research. Massachusetts Institute of Technology [1] reviewed the sensor networks as the top ten technologies that will change the world. A wireless sensor network consists of a group of sensors or nodes connected through a linked mechanism in order to perform distributed sensing work. Even though, wireless sensor networks can be deployed in the conditions, which are extremely critical from physical deployment. The application area of wireless sensor network ranges from military surveillance to the healthcare sector and many more areas are yet to be incorporated.

Such a tremendous growth in the wireless sensor networks has opened a new face of research in the field of distributed computing applications. Challenging [2] issues like scalability, coverage problem, localization, energy consumption and physical environment etc. must be addressed for the optimal performance of WSN system. For wireless and mobile environment, there is a great need of inexpensive and low power sensor node [3,5]. Analytical modelling of WSN and actual performance prediction are extremely difficult. Deploying test bed study in order to obtain the actual behaviour of WSN requires tremendous effort. In the future, we are expecting a lot of real time WSN application as one of the effort has already explored in the same field [4].

The breakdown of the paper is as follows. Section 2 defines the scalability, their design challenges and AODV protocol within the context of wireless sensor networks. In Section 3, we introduce the proposed evaluation model for WSN simulation framework for our experiment. The primary results of performance investigation based on scalability of wireless sensor network are shown in Section 4. Finally, in Section 5, we conclude with a resultant about the scalability issue in wireless sensor networks.
