This book constitutes the refereed proceedings of the 13th International Conference on Ad-hoc, Mobile and Wireless Networks, ADHOC-NOW 2014, held in Benidorm, Spain, in June 2014. The 33 revised full papers presented were carefully reviewed and selected from 78 submissions. The papers address such diverse topics as routing, cellular networks, MAC and physical layer, mobile ad hoc, sensor and robot networks, localization and security, vehicular ad-hoc networks.

This book brings together leading researchers and developers in the field of wireless sensor networks to explain the special problems and challenges of the algorithmic aspects of sensor and ad-hoc networks. The book also fosters communication not only between the different sensor and ad-hoc communities, but also between those communities and the distributed systems and information systems communities. The topics addressed pertain to the sensors and mobile environment.

Wireless sensor networks are being built to facilitate automated information gathering in military, industrial, environmental and surveillance applications. Many such applications of Sensor Networks require desired/pre-fixed QoS (Quality of Service: packetdata delivery within a defined deadline) guarantees and as well as high reliability. These applications demand high packet delivery ratio and are extremely delay sensitive and also demand reliability. However, certain factors limit the ability of the multihop sensor network to achieve the desired goals. These factors include the delay caused by network congestion, or hot regions in the network, limited energy of the sensor networknodes, packet loss due to the collisions and link failure andand mobilitylink failure. In this work, Our paper suggests an energy aware dual-path routing scheme for real timedeadline driven traffic is proposed, which balances node energy utilization, which is energy awareincreases the network lifetime, reducess the routing delay across the network by taking network congestion into account and increases the reliability of the packets reaching the destination by introducing minimal data redundancy. We als This paper also o introduces an adaptive prioritized Medium Access Layer (MAC) specifically to provide a differentiated service model for real time packets. Our intuitive claims areis well supported by simulationby simulation results.

This book provides comprehensive coverage of the major aspects in designing, implementing, and deploying wireless sensor networks by discussing present research on WSNs and their applications in various disciplines. It familiarizes readers with the current state of WSNs and how such networks can be improved to achieve effectiveness and efficiency. It starts with a detailed introduction of wireless sensor networks and their applications and proceeds with layered architecture of WSNs. It also addresses prominent issues such as mobility, heterogeneity, fault-tolerance, intermittent connectivity, and cross layer optimization along with a number of existing solutions to stimulate future research.
