Joint rate regulation and power control for cochannel interference limited wireless networks
Centralized and distributed algorithms for joint rate regulation and power control are proposed for the wireless networks where the cochannel interference limits the capacity. The goal of the proposed algorithms is maximizing the data rate while ...
Aggregation methods for integrated services
Reservation aggregation provides scalability to the IETF Integrated Services (IntServ) by reducing the high number of states stored at internal routers and the number of signaling messages processed at these routers. However, in the case of frequent ...
On the performance of two-way relay channels using space–time codes
In this paper, we explore the advantages of network coding and space–time coding in improving the performance of two-way-relayed communications where two terminals absent of direct links exchange information through a single relay in between. Network ...
A delay-based transport layer mechanism for fair TCP throughput over 802.11 multihop wireless mesh networks
Cities worldwide have planned and implemented large-scale wireless mesh network (WMN) deployments. These mesh deployments are expected to provide broadband mobile access to the Internet at a low cost to the user. This paper considers the fairness ...
A smart exponential-threshold-linear backoff mechanism for IEEE 802.11 WLANs
Based on the standardized IEEE 802.11 Distributed Coordination Function (DCF) protocol, this paper proposes a new backoff mechanism, called Smart Exponential-Threshold-Linear (SETL) Backoff Mechanism, to enhance the system performance of contention-...
Performance analysis of cooperative multi-carrier relay-based UAV networks over generalized fading channels
The outage probability in a network of cooperative unmanned airborne vehicles (UAVs) over generalized fading channels is studied analytically using finite mixture with expectation maximization technique. A relay-based topology with one ground control ...
A delay-oriented prioritization policy based on non-congestive queuing
In this paper, we depart from our previously proposed Non-Congestive Queuing (NCQ) mechanism and propose a new scheduling discipline that allows for efficient interoperation of dedicated systems (such as sensor and voice networks) with the Internet. ...
Performance study of mobile WiMAX network with changing scenarios under different modulation and coding
WiMAX—the Worldwide Interoperability for Microwave Access is a promising technology for offering high-speed data, video and multimedia services over mobile platform evolving toward all IP networks. The increasing demand of WiMAX for VoIP and high-speed ...
