Description: TOPIC: ENERGY AWARE CROSS LAYER PROTOCOL IN WIRELESS SENSOR
NETWORK
LOCATION: Lester W. Cory Conference Room, Science & Engineering Building (Group II), Room 213A
ABSTRACT:
Power constraints on the sensor boards have inhibited the Wireless Sensor Networks (WSN) from incorporating applications that require high transmission rate between collaborating nodes. In most WSN applications, replacing the batteries on the node is either an expensive or impossible task to achieve due to the geographical location and the topology of the deployed network. Therefore, the short lifetime of the energy source on the nodes has been the main motive for achieving an energy efficient sensor network.
A typical node in WSN consists of an on board battery, radio chip, memory, sensors, and a processor. Currently, radio chips are highly optimized and carefully designed to conserve energy. Without any technological breakthrough, the development of a new radio chip that would significantly conserve power compared to other optimized chip is a daunting task. For this reason, most of the efforts for conserving energy have been focused on energy aware software stack; the core of the work is centralized in the (Medium Access Control) MAC layer because it's the layer controlling the radio state. Radio transmission and reception operations are known to be the functionality that consumes most of the energy in WSN. This thesis proposes a methodology that extends the lifetime of the sensor network by reducing the size of the transmitted packets as well as the collision rate within a network. This will be accomplished by amalgamating Time Division Multiple Access (TDMA) and Frequency Division Multiple Access (FDMA) protocols in the MAC layer. Combining TDMA and FDMA reduces the energy wasted during idle listening period and permit the network to form a scatternet-like topology that would minimize interference, expand the network capacity, and enable very complex topologies.
Often, conserving energy comes at the expense of throughput, latency, and the elasticity of the network topology. The thesis touches upon novel approaches to maintain a minimal trade-off between energy conservation and other network parameters. Finally, a software was developed as a proof of concept to the theories provided in this thesis. The software acts as a WSN emulator and can be tuned and build upon in order to test, monitor, and analyze the behavior of WSNs.
