Abstract
Sony is looking into improving the overall performance and cost eciency for over-the-air (OTA) updates of new software into mobile de- vices. Consequently there is a cost associated with every new connection from a mobile device to the content delivery network (CDN), hereafter the server. Each device requires some amount of data and space from the server during the connection phase. Using a peer-to-peer (P2P) approach might help improve the cost eciency and performance of each new connection to the server also improving the overall eciency during an OTA update. The idea is that mobile devices will help each other, decreasing the round trip time from the server and instead connect to each other more closely in a mobile cell, likewise, reducing the amount of active connections to the server which implicates a reduction of costs. <p> The overall purpose of the thesis is to investigate if there is a performance increase and cost decrease, by using a single eort to implement a new protocol for the OTA updates. Hence, the main purpose is to understand if the single eort will be worth the cost for a longer prospect of time.
