| Abstract | Wireless ad hoc networks consist of hundreds to thousands of mobile nodes that are powered by batteries. To prolong the network operational time, energy conservation in such networks is of paramount importance. Energy optimization thus is one major objective in the design of routing protocols. However, in some stringent real-time applications including target tracking and bushfire surveillance, latency is an important concern, and little attention has been paid to it in the design of routing protocols for such applications to meet the specified Quality of Service (QoS) requirements like the end-to-end latency constraint. In this paper we focus on online energy-aware routing protocol design for routing requests to meet various end-to-end latency constraints under the multi-rate environment, we aim to maximize the network lifetime through striking the right balance among the node's transmission rate, the end-to-end latency, and energy consumption. Specifically, due to the NP-hardness of the problem of concern, we propose a joint optimization framework consisting of finding a routing path and assigning a specific transmission rate at each node in the path for each request such that the total energy consumption is minimized. We also devise novel heuristic algorithms for the problem, based on different energy cost metrics. We finally conduct extensive experiments by simulations to evaluate the performance of the proposed algorithms in terms of network lifetime. The experimental results show that the proposed algorithm incorporating the energy utilization ratio of the residual energy of a node to its initial energy capacity into the cost metric outperforms the others significantly. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
