Transport Layer Design in Mobile Wireless Networks

چکیده
In this chapter, we discuss the transport layer design issues in a mobile wireless networks. The focus will be put on two transport protocols: Transmission Control Protocol (TCP) and Stream Control Transmission Protocol (SCTP). TCP is the dominant transport protocol currently used for most Internet services such as Web browsing, file transfer, remote login etc. SCTP is a recently developed protocol by IETF for signaling message transport over IP networks, and it is being actively studied to explore its applicability to new arenas. Both these two protocols were mainly designed with wired network in mind. In mobile wireless environment, the performance of TCP and SCTP would be affected severely due to some issues such as low bandwidth, high packet error rate, user mobility, sudden delay spikes, etc. In this section, we explain the impact of these issues and the proposed schemes to improve the performance of TCP. The recent research effort in SCTP over mobile wireless networks is also surveyed.

3D Path Planning Algorithm for Mobile Anchor-Assisted Positioning in Wireless Sensor Networks
Positioning service is one of Wireless Sensor Networks’ (WSNs) fundamental services. The accurate position of the sensor nodes plays a vital role in many applications of WSNs. In this paper, a 3D positioning algorithm is being proposed, using mobile anchor node to assist sensor nodes in order to estimate their positions in a 3D geospatial environment. However, mobile anchor node’s 3D path optim...

Due to the resource constraint and dynamic parameters, reducing energy consumption became the most important issues of wireless sensor networks topology design. All proposed hierarchy methods cluster a WSN in different cluster layers in one step of evolutionary algorithm usage with complicated parameters which may lead to reducing efficiency and performance. In fact, in WSNs topology, increasin...

Heretofore several position-based routing protocols have been developed for mobile ad hoc networks. Many of these protocols assume that a location service is available which provides location information on the nodes in the network.Our solutions decrease location update without loss of query success rate or throughput and even increase those.Simulation results show that our methods are effectiv...

متن کاملA Survey of Solutions to Protect Against All Types of Attacks in Mobile Ad Hoc Networks
In recent years mobile networks have expanded dramatically, compared with other wireless networks. Routing protocols in these networks are designed with the assumption that there is no attacker node, so routing protocols are vulnerable to various attacks in these networks. In this paper, we review the network layer attacks and then we simulate the impact of black hole attack on ad hoc on demand...
