The modern information technology has the back born running over wireless sensor networks, because the people uses various services through the wireless devices like mobile, PDA and so on. Many applications are running over the wireless sensor networks and could be accessed through wireless devices and can be applicable for many solutions. The purpose of deployment of WSN is for data collection on the battlefield or any situation in a rapid manner which requires fast and reliable data collection. The channel assignment also the primary factor while collecting information from different layers of the node. The concept of data collection has been discussed in many situations and suffers from the problem of data collection and channel assignment. We propose a novel approach which assigns channels based on layers in the tree structure wireless sensor networks to collect the data from WSN. The proposed layer based approach uses time division multiple access where the nodes present in each layer of the tree will be discreteto each time slot. The method computes the density at each layer based on the data available or transmitted at the previous transmission. The scheduling and channel assignment is complete at each time slot, and the one step layered nodes will be remainingto thecanal. This permits the transmission of the nodes could be approved outcontinuously, and the node which does not have channel assignment will continue idle.
