Security for Multihop Wireless Networks

Multihop Wireless Ad Hoc Networks

An ad hoc network is a collection of mobile nodes using wireless network interfaces to communicate among themselves, discovering and routing along possibly multihop routes to each other without the assistance of fixed infrastructure. In this paper, we describe the design and demonstration of a set of simple routing protocol mechanisms that substantially improve the transmission of real-time mul...

Asynchronous Multimedia Multihop Wireless Networks

Personal communications and mobile computing will require a wireless network infrastructure which is fast deployable, possibly multihop, and capable of multimedia service support. The first infrastructure of this type was the Packet Radio Network (PRNET), developed in the 70’s to address the battlefield and disaster recovery communication requirements. PRNET was totally asynchronous and was bas...

Enabling Multihop Communication in Spontaneous Wireless Networks

Since the end of the 20th century, wireless networking is experiencing explosive growth, driven by the popularity of wireless telephony on one hand, and by the development of wireless computer networks on the other hand. Both trends are currently merging into a single attempt: enabling massive wireless Internet access. This phenomenon was inspired by Norman Abramson’s pioneer work on packet rad...

Increasing TCP Capacity in Wireless Multihop Networks

It is reported in the literature that a TCP connection with small window size achieves high throughput in wireless multihop networks. In this paper, we claim that TCP can benefit more from delaying ACK rather than limiting the window size. Since the induced delay may result in lengthy transfer time for short connections, we propose an adaptive delayed ACK algorithm at the receiver to enhance TC...
