Abstract
Dette projekt udvikler en analytisk model, der forudsiger throughput (datahastighed) og strømforbrug i et trådløst mesh-netværk, undersøgt i en enkel "Alice og Bob"-topologi. Vi præsenterer også et specialbygget MeasuringTool til at måle det faktiske strømforbrug i netværket. Med modellen og målingerne vurderer vi effekten af network coding – en metode, der kombinerer datapakker for at reducere antallet af transmissioner. Analysen viser, at network coding reducerer energiforbruget ved høj belastning, hvilket bekræftes af målingerne. Derudover peger både model og forsøg på, at network coding også giver fordele ved lav belastning.
This thesis develops an analytical model to predict throughput (data rate) and power consumption in a wireless mesh network, studied in a simple "Alice and Bob" topology. It also introduces a custom MeasuringTool to record actual power consumption in the network. Using the model and measurements, we assess the impact of network coding—a method that mixes data packets to reduce the number of transmissions. The analysis shows that network coding reduces energy use under high traffic loads, a result confirmed by measurements. Moreover, both the model and experiments indicate that network coding provides benefits even when traffic is light.
