Energy consumption is a vital resource to be controlled to extend the longevity of a wireless sensor network. In a multihop routing, lifetime as well as throughput of the network could be increased by selecting the forwarding node intelligently. The existing energy-aware routing protocols either do not jointly consider the network performance and energy(More)
Cognitive radio networks (CRNs) have received considerable attention and viewed as a promising paradigm for future wireless networking. Its major difference from the traditional wireless networks is that secondary users are allowed to access the channel if they pose no harmful interference to primary users. This distinct feature of CRNs has raised an(More)
Information Centric Networks (ICN) is proposed as an alternative design for content-based communication rather than host-to-host-based communication. In ICN architecture, the data are cached or stored at intermediate routers to satisfy future demands locally without repeatedly getting it from the original source. For ICN architecture to work efficiently,(More)
—In a typical cognitive radio network (CRN), secondary users can only access the channel when they do not harmfully interfere with the primary users. Therefore, an accurate estimation or prediction of interference from secondary users to primary users is essential. In this paper, we tackle the problem of interference estimation in a channel in presence of(More)
In a distributed control multi-hop wireless ad hoc network, multiuser interference plays a significant role in determining the network performance. Although the effects of hidden/exposed terminals on the system throughput in wireless ad hoc networks have been extensively studied, the multiuser interference power computation without as well as with(More)
The authors propose three variants of distributed and stateless forwarding strategies for wireless sensor networks, namely greedy minimum energy consumption forwarding protocol (GMFP), lifetime maximising GMFP (LM-GMFP) and variance minimising GMFP (VAR-GMFP), which aim at maximising the network lifetime while achieving a high forwarding success rate. GMFP(More)
—The extremely long propagation delay between interplanetary nodes poses challenges to the investigation of Store-and-forward Deep Space Autonomous Network (DSAN). Long propagation delay combined with scarcity of energy at the planetary wireless nodes and relays, introduces new dimensions to the congestion control challenge. In this paper, we take advantage(More)
Machine-to-Machine (M2M) communication is expected to be one of the major application areas of cellular communications in near future. In cellular M2M communication, although, the gateway layer provides smooth management to underlaying cellular networks, it over-burdens the network in terms of delay and bandwidth utilization. Therefore, with the recent(More)
