1. Mobile Ad hoc Network (MANET) :
MANET consists of number of mobile devices that are connected together to form a network, without any support from an existing internet infrastructure or any other fixed network station. It is autonomous system of nodes connected by wireless links. In MANET the network topology may change dynamically in an unpredictable manner since there is no fixed infrastructure and the nodes are free to move, but each node have limited transmitting power. MANET’s are basically peer-to-peer, multi-hop wireless network in which packets are transmitted in store.
2. Vehicular Ad Hoc Networks (VANET) :
VANET is similar to MANET in terms, that is also do not need any infrastructure for data transmission. VANET play important role in aspect of safe driving, intelligent navigation, emergency and entertainment applications .It can be defined as an intelligent component of transport system as vehicle are able to communicate with each other as well as roadside base station, which are located at critical points of the road. Example :-Intersection and Construction Sites.
Difference between MANET and VANET :
|1||Production cost of MANET is cheap as compared to VANET||Much Expensive|
|2||Mobility of MANET is low as it make bit difficult for network enables the serving networks to locate a mobile subscriber’s point.||High Mobility, as serving networks to locate a mobile subscriber’s point is easy.|
|3||Change in network topology orientation is slow.||Frequent and very fast change of network topology,|
|4||Sparse node density.||Node density is frequent variables.|
|5||MANET HAVE 100 Kps bandwidth available.||VANET bandwidth is 1000 Kps.|
|6||It ranges Upto 100 m.||500 m range available in VANET.|
|7||MANET node lifetime depends on power resources.||Depend on lifetime vehicle.|
|8||MANET have medium realiability.||High reliabilty of VANET.|
|9||Movement of the nodes affects the operation of a MANET as node movement MANETs need to rely on robust routing protocols.And this MANET have random node movement.||Regular, moving pattern of nodes.|
|10||Attribute Based addressing scheme.||Location Bases addressing scheme.|
|11||Position acquistion is obtained using Ultrasonic.||VANET maintain position acquistion by using GPS, RADAR.|
|12||Availability of Multi-hop Routing||Weakly available Multi-hop Routing.|
