Thesis (Ph.D.)--University of Minnesota, 2003.

Ad Hoc Wireless Networks are automated and infrastructureless. An ad hoc network can be formed on the fly and changed dynamically. In ad hoc wireless networks, some intermediate nodes are needed and the communication will be multi-hop if the destination is not within the transmission range of the source. It can be widely used in any inhospitable terrain. It provides the technology for pervasive computing.Subjects--Topical Terms:

520 $a Ad Hoc Wireless Networks are automated and infrastructureless. An ad hoc network can be formed on the fly and changed dynamically. In ad hoc wireless networks, some intermediate nodes are needed and the communication will be multi-hop if the destination is not within the transmission range of the source. It can be widely used in any inhospitable terrain. It provides the technology for pervasive computing.
520 $a In this dissertation, I first study the unicast routing protocols of Ad Hoc Wireless Networks. A group of routing protocols use virtual back bone, which is the core or forwarding group within the networks. We design a Polynomial-Time Approximation Scheme for the connected dominating set in unit disks, which implies the current routing protocols with the best performance ratio 8 can be greatly improved.
520 $a Next, a distributed routing protocol which is time and message efficient is presented. This protocol uses asynchronous and distributed algorithm to construct the virtual backbone for the ad hoc wireless networks. It also introduces the cost metric that is related to battery capacity and communication state. This routing protocol minimizes the total cost of the network by selecting low cost nodes to construct the virtual backbone.
520 $a Broadcasting is very useful in the alarm system, route discovery process of on-demand routing, route update in table-driven routing etc. A cost-aware broadcast protocol is presented. It constructs a multipoint relay set using a distributed asynchronous approach. Only one-hop neighbor information is needed for each node, so the computation is localized. This protocol uses the same cost metric as above so that it uses nodes with high battery capacity, low existing communication traffic, and high communication capacity, therefore the broadcast is reliable. It keeps the number of node in the multipoint relay set to minimal to achieve broadcast efficiency.
520 $a The problem of Steiner tree with minimum number of Steiner vertices in unit disk graph is studied in the last. This technique is applied to approximate the minimum connected dominating set, and the performance ratio is 7, which is currently the best performance ratio.
