Wireless communication consumes a significant amount of energy in wireless networks. Most multi-hop wireless routing protocols are adopted from wired network routing protocols and use pre-selected single or multiple minimum cost paths to forward data packets. However unlike wired networks, a wireless network has unique characteristics such as unreliable wireless links and multiple receivers ass...

The rapid movement of Vehicles which results in frequent changes in vehicle position and speed, as well as inaccuracies in predicting driver’s direction at intersections usually lead to wrong packet forwarding decisions in VANET. Consequently, a routing protocol incorporating vehicle density, moving direction and speed into GPSR in making packet forwarding decisions is hereby proposed. Key data...

Data delivery of packets in broad cast using wireless medium is the main intention of this paper, this will be done through a MANETS and should achieve reliable delivery. To do this various protocols are available in the networks world with in that efficient protocol called Position based opportunistic routing protocol which hold stateless property of geographic routing. When a data packet is s...

Programable Network Processors(NPUs) are embedded system-on-chip multiprocessors optimized for packet processing and forwarding tasks at line speeds. To meet the demands of increasing data rates and complex network applications, current architectures of NPUs are implemented with several embedded processor cores (or microengines) to induce parallelism in packet processing tasks. In this paper we...

Recent work in sensor network energy optimization has shown that batch-andsend networks can significantly reduce network energy consumption. Batch-andsend networks rely on effective batch data transport protocols, but the throughput of state-of-the-art protocols is low. We present conditional immediate transmission, a novel packet forwarding mechanism, with which we achieve a 109 kbit/s raw dat...
