Abstract :

Ad hoc Sensor Network (ASNs) is distributed systems which consist of wireless mobile or static sensors. In order to
communicate with each other, each mobile unit must act as a router and a terminal, and must retransmit packets from
other mobile units. Due to their great flexibility of use, good robustness and very quick deployment, such networks can be
used in many areas. The applications developed in such areas use especially multimedia and real-time data (images, video, etc.).
ASN’s users would like to have the same services as those offered by wired networks. In other terms, the applications used in
wired networks must be functional in ASNs, especially multimedia and real-time applications (video conferencing, internet
telephony, video on demand etc.). The limited sizes of the sensors make complex, the support of such applications which
require significant resources like the energy, bandwidth, delay, losses rate, jitter, QoS etc. Many factors, at different levels of the
network (physical, MAC, routing and transport) reduce the performance of these networks. We then see appeared specificity
of some protocols such as MAC, routing and transport with the support of multimedia applications and data.
