VDM NWIZEGE, K: Analysis of QoS for Mission Critical Services ov

Multimedia application is currently making much impact in this technological era. It has been the key driving force behind the convergence of fixed, mobile and IP networks. Furthermore, real-time applications are making head way in vehicular networks, mission critical applications which use dedicated short range communications (DSRC). Wireless networks have emerged so well and become popular as they are deployed in almost every sector of life such as Schools, hospitals, coffee shops, airports, restaurants etc. Modern mobile devices such as laptops, PDAs are capable of deploying these services. The interesting thing is that, multimedia services such as voice over internet protocol (VoIP), video can be deployed using wireless technology known as WLAN. 802.11e is medium access control (MAC) is an emerging supplement to the IEEE 802.11. IEEE802.11e standards deals with Quality of Service (QoS), with the help of it mechanisms like EDCF. But 802.11p which is mainly for vehicular network,will perform better in analysing QoS in vehicular networks. This analysis will help reduce road accident, traffic congestion, safety etc.
