Rate, energy and delay are three main parameters of interest in ad-hoc networks. In this paper, we discuss the problem of maximizing network utility and minimizing energy consumption while satisfying a given transmission delay constraint for each packet. We formulate this problem in the standard convex optimization form and subsequently discuss the tradeoff between utility, energy and delay in such...
Nodes in ad hoc networks can be unfairly burdened to support many packet-relaying functions, resulting in excessive loads on these hot spots. This load on nodes appears in two major aspects: traffic and power consumption. Unbalanced traffic may lead to more delay, packet dropping, and decreasing packet delivery ratio (PDR). Unbalanced energy consumption leads to node failure, network partitioning...
Wearable computers need networking by using wireless ad hoc network in order to utilize them more effectively, routing protocol becomes an important research field for its significance in wireless ad hoc network. In Ad Hoc network, there are mainly two kinds of routing protocols: proactive routing protocol and on-demand routing protocol, to evaluate the performance of two kinds of protocols, we choose...
Sink mobility has become an increasingly important requirement of various sensor network applications. Handling such mobile sink conditions brings new challenges to large-scale sensor networking. This investigation proposed a hybrid-structure routing protocol (HSRP) that combines the benefits of grid-based and cluster-based structures. Grid-based structure is designed to solve the cluster head selection...
