The major requirement of wireless sensor network is the energy efficiency. It is the MAC where designing such type of MAC protocols which fulfill the desires of the network and energy efficiency can also be achieved. There are a lot of applications in which the requirement are different and a MAC protocol is not efficient for these types of application. Here we describe a new protocol D-TDMAC, based on TDMA MAC, designed for dynamic sensing applications. CH is responsible for allocating slots to the nodes. The free slot is efficiently used by the other nodes which require more slot. Interference due to intra cluster or inter cluster communication is avoided by D-TDMAC. Overhearing is also significantly eliminated.
