چکیده:

In this paper we propose a key management scheme for an application of wireless sensor networks.Our application consists of a number of clustered sensor nodes that measure the pressure in waterpipelines. Sensor nodes communication is based on the IEEE802.15.4 standard by the help ofZigbee modules. The data is collected in 15-minute period intervals and is sent via GPRS to the control center. The main purpose of this research is to identify the unbalanced water pressuredistribution problem in cities. We chose the key management scheme to be the suitable solution for our application. As our application with its large scale sensor network deployment and layout, is in a sensitive and vulnerable to the intruders in a hostile environment, we introduced and tested oursystem with a different disruptions scenario and based on the collected result we came up with the ISECK security package in order to have a strong resilience network against node captures. ISECK is an improved version of survivable and efficient clustered keying protocol. We also considered the energy efficient protocol. According to the test results and simulation we show that our protocol is more energy efficient and stronger than the previoulsly proposed SECK.
