Simulation of Scalable Streaming Protocols using Wireless Multicast/Broadcast

Abstract: In a society where the popularity of mobile video streaming increases, the need to understandthe affect on the power consumption on mobile devices increases. This thesislooks into which broadcasting protocol to use when trying to optimize the energy consumptionand startup delay while receiving a video from a transmitting source using scalablestreaming protocols. This thesis evaluates four different scalable streaming protocolsand how much power mobile clients consume when receiving a video over different numberof channels and how different interfaces such as 3G and WiFi affect the power consumption.The protocols are simulated using our own written simulator and a tool calledEnergyBox, which simulates both 3G and WiFi connections. The thesis also compares theprotocols with each other in two ways, the amount of energy consumed and how longthe startup delay is for each protocol. Based on these simulations and comparisons weconclude which protocol of these four provides the best energy-delay tradeoff. The resultshows that the energy consumption while usingWiFi is much less than when using 3G. FastBroadcasting is also far superior the other protocols when it comes to energy consumption.When it comes to startup delay the protocols are very even.
