WTP: bandwidth-efficient and reliable cross-layer transport protocol for MANETs
نویسنده
چکیده
Performance and adaptability of the transport protocol are among the most critical parts of the TCP/IP protocol stack since it is directly related to the user interaction and application experience. In this paper we analyze specific problems of reliable transport protocol performance caused by rapidly changing topology in MANETs in addition to classical transport layer challenges. Then we propose Wireless Transport Protocol (WTP) a new lightweight, bandwidth-efficient and reliable cross-layer transport protocol capable to adjust its performance to highly dynamic environment as MANETs. Experimental results show that simplifying protocol overhead, its processing and cross-layer optimization enables more precise adjustments to network and connection fluctuations, hence increasing transport protocol efficiency up to 19% in different conditions compared to standard TCP protocol (RFC793, RFC2581). Keyword—MANET, TCP, transport protocol, cross-layer, reliable data transfer.

Adaptive Link-Weight Routing Protocol using Cross-Layer Communication for MANET
Routing efficiency is one of the challenges offered by Mobile Ad-hoc Networks (MANETs). This paper proposes a novel routing technique called Adaptive Link-Weight (ALW) routing protocol. ALW adaptively selects an optimum route on the basis of available bandwidth, low delay and long route lifetime. The technique adapts a cross-layer framework where the ALW is integrated with application and physi...

MANETs are networks capable of communicating in a set of small, low cost, low power sensing devices. A wireless sensor networks is totally based on the limiting factor i.e. energy consumption. A wireless sensor network consists of large number of sensor nodes distributed or scattered in particular network region. MANETs consist of node that is highly mobile, so in particular the range of the no...
