Rapidly Gathering Iinformation in Wireless Sensor Networks using Demand Assigned Multiple Access (DAMA) with Multiple Access Collision Avoidance (MACA)

Abstract

The most essential application in Wireless Sensor Network (WSN) is Data gathering. The converge cast is method for collecting the data from several sensor nodes to sink node. During data gathering, there is the possibility of occurring collision, retransmission etc. One of the major problems in data gathering is collision. To deal with this particular data collection problem, several techniques are proposed for efficient and fast data collection in Wireless Sensor Network. This paper uses Demand Assigned Multiple Access (DAMA) to maintain scheduling protocol for data gathering in the depiction of tree-based structure in which the packets are collected based on the user demand within the communication range and Multiple Access with Collision Avoidance (MACA) provides fast data transmission due to avoiding the collisions which provides an efficient result. Thus the throughput has been increased and delay reduced for data collection in wireless sensor network. Keywords: Data Collection, DAMA, MACA, TDMA, Wireless Sensor Network
