| Abstract | The ever-increasing demand for multimedia surveillance and monitoring has led to the deployment of wireless sensor networks capable of capturing multimedia contents along with the scalar data. However, most of the routing protocols designed for wireless sensor networks (WSNs) are meant only for homogeneous sensor networks in which all sensor nodes have same capabilities in terms of communication, computation, energy supply, etc. This paper presents an ant-based QoS routing protocol for Heterogeneous Wireless Sensor Networks consisting of scalar and multimedia sensor nodes with diverse QoS requirements. The proposed protocol proposes different path selection criteria for control traffic and data traffic. The data traffic is further categorized into multimedia traffic and scalar traffic and QoS routes are selected according to the traffic type, thus improving network performance. Further, prior to actual deployment of such networks, an extensive evaluation of the protocols is carried out by making use of simulators. A simulator must replicate realistic conditions and one of the most difficult aspects is the radio signal propagation model. This paper shows that the non-determinism present in some radio propagation models induce randomness which may compromise the performance of many protocols and demonstrates the effectiveness of proposed protocol over AODV under different propagation models. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
