In this paper, we study the delay performance of wireless network considering different resource allocation schemes with single-hop traffic. Existing works studying the delay performance only consider a given resource allocation scheme, either multi-channel system (sharing bandwidth) or time slotted system (sharing time). The fundamental question ignored is which type of resource allocation scheme...
In this paper, we introduce an extension of Stream Control transmission Protocol (SCTP) aiming for improving the efficiency of delay-sensitive transmission of multimedia data such MPEG-4 traffic. Briefly, our SCTP extension exploits one-way delay between SCTP endpoints, which allows the SCTP extension to retransmit lost packets selectively depending on whether the lost packets would still arrive before...
In this paper we study the problem of collaboration in RF-Sensor networks, comprised of a large number of very small and low cost nodes, capable of sensing, communicating and computing. The Multi-phases Collaboration of such nodes may lead to the accomplishment of large sensing tasks, having useful applications in practice. First, we research two collaboration methods, one is no collaboration and...
This paper introduces the reservation packet medium access control (RP-MAC) protocol for wireless sensor networks (WSNs). The protocol incorporates a periodic listen/sleep schedule to conserve energy and employs a novel channel reservation mechanism to enhance the rate at which packets can be transferred over multiple hops, thereby improving throughput and reducing end-to-end delay. To evaluate the...
