With the huge advancements of mobile computing due to the enormous increase in portable wireless devices, Mobile Ad hoc Networks (MANETs) became an important aspect in the world of wireless network communications. With some unique features such as scalability, fault tolerant and autonomous systems enable a network to be setup with or without any trusted authority. This makes MANET suitable for the emergency and rescue operations. During an emergency situation, there is a need for the data to be shared with the rescuers. Prior accessing the information in emergency services, nodes in MANET need to be authenticated. However due to wireless nature that MANET inherit, nodes are susceptible to attacks hence a secure authentication mechanism is required as authentication is the first defend mechanism. This paper review the authentication models in MANET and proposed the suitable model to work under our proposed access control model called Heterogeneous Access Control Model (HACM). HACM is an expanded proposed model from our Group Based Access Control Model (GBAC) where access to information is classified into general and sensitive based on the Group Role (GR) and User Role (UR) of rescue members during emergency services. The HACM model introducesHeterogeneous Access Level (HLA) where access to information is based on level of information sensitivity, which is mapped with user-role in the group, created at the emergency area. The level of information sensitivity depends on how disastrous or the severity of the emergency situation.

“…Proactive protocols rely upon maintaining routing tables of known destinations, this reduces the amount of control traffic overhead that proactive routing generates because packets are forwarded immediately using known routes, however routing tables must be kept up-to-date; this uses memory and nodes periodically send update messages to neighbours, even when no traffic is present, wasting bandwidth [10]. Proactive routing is unsuitable for highly dynamic networks because routing tables must be updated with each topology change, this leads to increased control message overheads which can degrade network performance at high loads [11].…”

“…Distance vector routing uses next hop and destination addresses to route packets, this requires nodes to store active routes information until no longer required or an active route timeout occurs, this prevents stale routes [10]. Flooding is a reliable method of disseminating information over the network, however it uses bandwidth and creates network overhead, reactive routing broadcasts routing requests whenever a packet needs routing, this can cause delays in packet transmission as routes are calculated, but features very little control traffic overhead and has typically lower memory usage than proactive alternatives, this increases the scalability of the protocol [1].…”

Abstract-The increase in availability and popularity of mobile wireless devices has lead researchers to develop a wide variety of Mobile Ad-hoc NETworking (MANET) protocols to exploit the unique communication opportunities presented by these devices. Devices are able to communicate directly using the wireless spectrum in a peer-to-peer fashion, and route messages through intermediate nodes, however the nature of wireless shared communication and mobile devices result in many routing and security challenges which must be addressed before deploying a MANET. In this paper we investigate the range of MANET routing protocols available and discuss the functionalities of several ranging from early protocols such as DSDV to more advanced such as MAODV, our protocol study focuses upon works by Perkins in developing and improving MANET routing. A range of literature relating to the field of MANET routing was identified and reviewed, we also reviewed literature on the topic of securing AODV based MANETs as this may be the most popular MANET protocol. The literature review identified a number of trends within research papers such as exclusive use of the random waypoint mobility model, excluding key metrics from simulation results and not comparing protocol performance against available alternatives.Index Terms-AODV, MANET, routing protocols. I. INTRODUCTIONWireless technologies such as Bluetooth or the 802.11 standards enable mobile devices to establish a Mobile Ad-hoc Network (MANET) by connecting dynamically through the wireless medium without any centralised structure [1]. MANETs offer several advantages over traditional networks including reduced infrastructure costs, ease of establishment and fault tolerance, as routing is performed individually by nodes using other intermediate network nodes to forward packets [2], this multi-hopping reduces the chance of bottlenecks, however the key MANET attraction is greater mobility compared with wired solutions.There are a number of issues which affect the reliability of Ad-hoc networks and limit their viability for different scenarios; lack of centralised structure within MANET requires that each individual node must act as a router and is responsible for performing packet routing tasks; this is done using one or more common routing protocols across the MANET [3]. Performing routing tasks requires memory and computation power, however mobile devices feature physical size and weight limitations essential for their mobility, this Manuscript received September 6, 2012; revised December 12, 2012.
