In this paper device-to-device (D2D) communication is proposed as a tool for enhancing the services provided by mobile cellular networks. The technique we discuss relies on the cooperation among the mobile users that participate in the service delivery process, under the control of the base station. In particular, the paper proposes an incentive mechanism encouraging terminals to organize into an...
Current mobile terminals are equipped with several network interfaces, which may be of different access technologies, both wireless and cellular. With multi-homed terminals, it becomes possible to use simultaneously the various interfaces - and not only to handoff from one to another. Furthermore, it becomes possible to associate the suitable interface to each application according to its requirements...
This paper presents a method to reduce the computation and memory access for variable block size motion estimation (ME) using pixel truncation. Previous work has focused on implementing pixel truncation using a fixed-block-size (16 times 16 pixels) ME. However, pixel truncation fails to give satisfactory results for smaller block partitions. In this paper, we analyze the effect of truncating pixels...
