Connectivity in energy balanced traffic distribution

For many sensor network applications such as wild fire detection and battlefield surveillance, it is necessary to minimize energy consumption and extend system lifetime by leveraging the redundant deployment of sensor nodes while at the same time provide full sensing coverage and communication connectivity. An energy balanced stochastic based traffic distribution (SBTD) has been introduced in J. Wang and I. Howitt (2005), which has the target to prolong the network´s lifetime. Thus, SBTD can be used to provide efficient communication connectivity in the future routing paradigm. This paper investigates the connectivity of the wireless sensor networks using the SBTD in a log-normal shadowing environment. Our main contributions include: (i) the effective communication coverage of nodes in the network using the SBTD is derived; (ii) the network connectivity and the parameters affecting the network connectivity are discussed and investigated; (iii) and the system accuracy using different values of the optimization parameter is discussed
