Maximum battery life routing to support ubiquitous mobile computing in wireless ad hoc networks

“…The use of excessive transmission power can increase the interference to other hosts and will cause an increase in transmission power by other hosts. Therefore, physical layer functions should include transmitting data at the minimum power level to maintain links, and adapt to changes in transmission environment (due to host mobility or co-channel interference) [5]. Summarizing, power control can maintain a link at the minimum power level, but can also prolong an existing link against interference by increasing the transmission power.…”

“…This reduces the possibility of transmission errors but increases the signalto-interference ratio (SIR) of the network. Therefore, to appropriately determine when and at what power level a mobile host should attempt retransmission is an important issue for minimizing power incurred at the data link layer [5].…”

Quality- Of- Survey Routing Solutions forMobile Ad HocNetworks: A Review

“…The objectives of QoS routing are threefold: (1) if one exists, find a feasible path between a source destination pair (i.e. a path that has sufficient available resources capable of satisfying the QoS requirements), (2) optimize the use of network throughput and network resources and (3) adapt to network congestion, providing smooth performance degradation to lower-priority traffic. The QoS routing protocol tries to find a path that has a good chance of meeting the QoS requirements [21].…”

Throughput and delay analysis of wireless random access networks

“…This issue did not draw much attention until the emergence of wireless ad-hoc networks [4]. In contrast to cellular systems, nodes not only generate their own packets, but also relay others' packets in wireless ad-hoc networks.…”
