An Expanded Distributed Address Assignment Mechanism for Large Scale Wireless Sensor Network

Now the address assignment mechanism of wireless sensor network has a limitation on supporting large scale sensor network that is consisted of more than hundreds of nodes. A distributed address assignment that is indicated in ZigBee Alliance, the standard group related to WSN is a method assigning the address by dividing address area of 16bit into regular blocks according to the depth. But this method has a limitation on expanding network or effective usage of address because it assigns the address uniformly according to the value given at first. This essay comes up with an idea to effectively use reserved address of 16bit address area, which is excluded from the initial value and shows the result with simulation analysis.
