error-aware and energy-efficient routing approach in manets Beatty, Oregon

Section 4proposes our energy-efficient routing protocols termed multi-threshold routing protocol (MTRP)and enhanced multi-threshold routing protocol (EMTRP). Thus, everynode may have to serve as the intermediate node to relay the packets between a pair of nodesgeographically far enough. This approach thus avoids overusing certain routes and achieves load balancing. One of the states is error state; the other iserror-free state.

in 1999. Int. YANG AND S. The transition matrix R is given byR =1− ppr 1−r(4)So the duration of error state is a geometric random variable with mean (1/r)×tbadand similarlythe mean time in error-free state is (1/

Any failure of node may result in disconnection between a pair ofcommunicating nodes.Wireless devices are often battery powered, which means that power should be used extremelyefficiently to maintain the connectivity of InCopyright q 2008 John Wiley & Sons, Ltd.

Inaddition, if the transport layer protocol used by the nodes are ACK-enabled protocol, then ACKcan be used for probing if there are some ACK packets waiting for sending, otherwise the receiversends Syst. 2009; 22:37–51DOI: 10.1002/dac ENERGY-EFFICIENT ROUTING APPROACH 51AUTHORS’ BIOGRAPHIESLiansheng Tan is now with Research School of Information Sciences and Engineering,The Australian National University, Canberra ACT 0200, Australia. Did you know your Organization can subscribe to the ACM Digital Library? Algorithm for perfect channelInspired by the previous work such as CMMBCR, we propose our algorithms termed MTRP forthe case of perfect channel.

If the CTS is not receivedwithin a predetermined time interval, the sender retransmits the RTS packet. Example topology of feedback mechanism.Table V. If there are too few thresholds, the benefit of load balancing will diminish.Therefore, in future study, we will use fuzzy-based algorithms to dynamically adjust the numberof thresholds.ACKNOWLEDGEMENTSThis work was supported by In MTRP, multiple thresholds are introduced to achieve thetradeoff between balancing of energy consumption and the minimum total transmission power.

Please try the request again. Thresholds are set so that the initial energy is evenly divided. Thus, the whole route requiresenergy Pl=D−1i=0p(ni, ni+1), where n0and nDare source and destination, respectively.So the scheme aims to choose the route with minimum energy consumption Po= minl∈APl,where A is the set Commun.

To prolongthe lifetime of MANETs, one is forced to attain a tradeoff of minimizing the energy consumption andload balancing. From the state diagram, we have the expected number of transmissiongiven by the following equation [17]:Et=1p∗RTSp∗CTSp∗DA TAp∗ACK+1p∗CTSp∗DA TAp∗ACK+1p∗DA TAp∗ACK+1p∗ACK(3)From (3) the transmission attempt is a function of the channel’s ALP. When no route satisfies the condition, similar to MMBCR,it chooses a route with the minimum cost. Here, average frame error rate (FER) is used for this purpose.We use two different models to generate error packets.

CHANFor lossy channel, besides residual energy, the ALP is also required.

First, N0checks each route in its route cache tosee whether this route contains the sender who sends packets to it. INTRODUCTIONMobile ad hoc networks (MANET) consist of a set of autonomous mobile wireless nodes distributedin a certain area forming temporary (ad hoc) networks without any infrastructure. More will be continuously added in and the scope of coverage will be further extended by phases.
