MP2P Network in Collecting Data from Sensor Networks

Wireless sensor networks provide numerous applications today. At the same time modern wireless short-range communication technologies combined with mobile users create environments for mobile peerto- peer networks. This paper discusses a concept of an application in which an MP2P network is used for collecting sensor network data. This model requires certain places with a high mobile user density in order to function. Simulation results indicate that the model can be used in environments where these requirements are met.

1. Introduction

While the popularity of advanced smart phones and communicators has grown, and new short-range wireless communication technologies have emerged, P2P systems previously only used in the fixed networks have spread to the mobile world as well, hence creating the concept of a mobile peer-to-peer system, MP2P. There are two variants of MP2P environments: In the first variant, mobile nodes located near each other establish bilateral temporary connections [5]. It can be considered a special case of ad hoc networks. Even though ad hoc networks generally enable any network node to communicate with any other node in the network, via an intermediate node [2], if necessary, this paper concentrates only on single-hop communication, i.e. only local communication with an adjacent node. In order for this to work, the environment must contain a high density of MP2P users. The single-hop MP2P communication model presented in this paper is therefore well suited for highly-populated areas.
