Power Efficiency Analysis Anthony Donohoe z3293276 Tristan Morgan z3207705 Of Wireless Access Points, for Mesh Networking Power Efficiency Analysis

Introduction Wireless Mesh Network: Arbitrary Topology

Motivation Power use is important for mesh networking applications for the following reasons: Some nodes will be powered by PoE Some may be battery powered The mesh may be temporary, or outdoors It may be powered from a generator

Proposal To simulate the power use of a typical Wireless AP with various throttling schemes.

Parameters Three discrete bandwidths; since the bandwidths are relative (representing having between 1 and 3 antennae on), we will simplify them to 10Mbps, 20Mbps and 30Mbps. Set the average packet size to 1250B, and the queue size to 50KB. Also set lambda to 2 packets/ms (20Mbps).

Results

Conclusions The trade off is between power usage and packets dropped/throughput. We can get very good power usage, but at the cost of almost half the packets dropped. The best seems to be {5,15,6,15}, with a power usage of 1.81W, and 0.0139% packet loss.
