Abstract—With the increasing demand for real time applications in the Wireless Senor
Network (WSN), real time critical events anticipate an efficient quality-of-service (QoS)
based routing for data delivery from the network infrastructure. Designing such QoS
based routing protocol to meet the reliability and delay guarantee of critical events while
preserving the energy efficiency is a challenging task. Considerable research has been
focused on developing robust energy efficient QoS based routing protocols. In this paper,
we present the state of the research by summarizing the work on QoS based routing
protocols that has already been published and by highlighting the QoS issues that are
being addressed. The performance comparison of QoS based routing protocols such as
SAR, MMSPEED, MCMP, MCBR, and EQSR has also been analyzed using ns-2 for
various parameters.

Abstract-Due to recent developments in technology and uniquely distinct characteristics of MANETs, the
applicability of MANETs have become pervasive. As the applications are increasing, the vulnerability of these
networks against various attacks has been exposed. MANETs have not clearly and explicitly stated defense
mechanisms, so attacker node can easily disrupt the whole system or may take control over the information in
the network. Different types of attacks have been introduced by attackers and every attack has its distinct impact
on the network. Security is a paramount concern in mobile ad hoc network (MANET) because of its intrinsic
vulnerabilities .In this paper state-of-the-art security issues in MANETs are investigated. In particular t a survey
on different types of attacks and their different classifications is presented.
