Hop-by-Hop Transport Control for Multi-Hop Wireless Networks
TCP can perform poorly in multi-hop wireless networks due to problems with contention and poor feedback from end-to-end control algorithms. This thesis explores the design of a hop-by-hop transport protocol (HxH). By allowing intermediate nodes to actively participate, the protocol can respond more …

Load Balancing in Hop -by -Hop Routing With and Without Traffic Splitting
Traffic engineering (TE) is crucial in hop-by-hop OSPF networks. We present a novel, edge-based traffic engineering method to approximate the optimal traffic allocation. The new method uses bandwidth-sensitive hop-by-hop routing algorithms as its core. It has three significant advantages. First, it …

Relay Selection Strategies for Multi-hop Cooperative Networks
… several relay selection strategies for multi-hop cooperative networks. The relay selection strategies we propose do not require a central controller (CC). Instead, the relay selection is on a hop-by-hop basis. As such, these strategies can be implemented in a distributed manner. Therefore, …

Routing and Transport Layer Protocols for Wireless Networks
… a congestion control mechanism which uses hop-by-hop rate control with back-pressure. We show that our protocol has improved fairness properties compared to TCP based protocols.

Loop detection and prevention mechanism in multiprotocol label switching
… thread algorithm is based on running a thread hop by hop before the labels are distributed inside a MPLS Cloud Since the path for the data packets is set beforehand, the loop formation occurs at the control path. The shortest paths between selected source and destination have been calculated …

Techniques for mitigating congestion in wireless sensor networks
… data has to traverse a larger number of radio hops. Congestion control in wired networks is usually done using end-to-end and network-layer mechanisms acting in concert. However, this approach does not solve the problem in wireless networks because concurrent radio transmissions on different …

Fairness in a data center
… (DCB), is a new set of standards defined by the IEEE to make Ethernet lossless even in the presence of congestion. As with any new networking technology, it is critical to analyze how the different protocols within DCB interact with each other as well as how each protocol interacts with …

Traffic Control in Packet Switched Networks
… The first solution is the shortest path hop-by-hop routing deployed with the OSPF or IS-IS routing protocol and the IP forwarding protocol. This is the initially deployed and still the most popular routing solution in the Internet. The second solution is explicit routing implemented with …

Study of Techniques For Reliable Data Transmission In Wireless Sensor Networks
… to the dense deployment of nodes in WSN, multi-hop communication can be applied to mitigate the transmit power for sending bits of information, i.e., gathered data by the sensor nodes to the destination node (gateway) compared to single-hop scenarios. In our approach, we achieve a reasonable …

Application-specific reliable data transfer in wireless sensor networks
… for data loss. The protocol is based on hop-by-hop detection and recovery of lost data packets, out-of-sequence forwarding of packets and delayed request for missing packets at each node with non-acknowledgement of packets at each receiving node. We present a detailed analysis of the …

Design and Analysis of Adaptive Fault Tolerant QoS Control Algorithms for Query Processing in Wireless Sensor Networks
… MTTF of the system is maximized. We develop a hop-by-hop data delivery (HHDD) mechanism and an Adaptive Fault Tolerant Quality of Service Control (AFTQC) algorithm in which we utilize "source" and "path" redundancy with the goal to satisfy application QoS requirements while maximizing the …
