Nowadays, Restaurant is one of the most important factors in the choice of holiday destinations for tourists and contributes to the development of the local economy. This research is an initial attempt to investigate consumer behavior (tourist behavior) and the attitude of restaurant managers to the application of innovation and information and communication technology (ICT) in hotel restaurants. On the basis of the results of this study it can be concluded that tourists and restaurant managers in the city of Isfahan are interested in exploiting the application of innovation and ICT in hotel restaurants.
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 and decreases network lifetime and route reliability. Existing approaches try to improve the performance of routing protocols with respect to traffic balancing or energy consumption balancing, but most lead to drawbacks such as more delay, blocking, or dependence on global information from all nodes. In this paper we improve the well known Dynamic Source Routing (DSR) protocol to the so called Load Balanced DSR (LBDSR) protocol. We modify the RREQ (Route Request) and RREP (Route Reply) messages in DSR in order to maintain the remaining energy of intermediate nodes which forward RREQ and RREP. Route structure, available in the nodes cache, is modified so that the remaining energy of nodes can be calculated. LBDSR shows better traffic balancing and energy consumption balancing, end-to-end delay and route reliability metrics than DSR. Furthermore, LBDSR can also be customized to achieve better performance with respect to each of these metrics instead of being a trade-off between them.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
