Mobile wireless networks consist of a set of cooperative and
mobile nodes, each node can move randomly at a specific speed
in all directions without any control of a central manager. This type
of networks has become a hot research topic due to its
military
application and suitability for emergencies and natural disasters.
Due to the lack of fixed infrastructure, the routing process
becomes the major problem in this type of networks, where the
responsibility of routing is transferred to each node. Over the last
few years, a number of traditional routing protocols has been
proposed, but these protocols do not support quality of service in
different environments.
Some studies have improved some of these protocols to support
quality of service for specific environments. This research
identifies and analysis some of these improved protocols.
The low cost, ease of deployment has exposed WSNs an attractive choice for numerous applications,like environmental monitoring applications , security applications, real time tracking, and so on.
But in reality, these networks are operated on batte
ry with limitations in their computation capabilities, memory, bandwidth ,so they called networks with resource constrained nature, and this impels various challenges in its design and its performance.
Limited battery capacity of sensor nodes makes energy efficiency a major and challenge problem in wireless sensor networks. Thus, the routing protocols for wireless sensor networks must be energy efficient in order to maximize the network lifetime.
In this paper we simulated LEACH,SEP,DEEC,TEEN routing protocols and evaluated their performance by comparing with DT routing protocol in Homogeneous and Heterogeneous Wireless Sensor Networks on MATLAB.
In this paper, we use NCTUns 6.0
to simulate this kind of networks ,because it is difficult to do that is the
real world .In this paper, two routing protocols (AODV, ADV) are
studied within many scenarios to achieve their performances and
reliabi
lity using many metrics.
We conclude that ADV routing protocol adapts quickly when the
complexity of network and mobility of nodes increase. This is achieved
by varying the size and frequency of routing updates.

Vehicular Ad Hoc Network (VANET) is a form of Mobile Ad Hoc
Networks, but the nodes of this network are vehicles with special equipment to enable
them to communicate with each other. These networks need to implement protocols to
ensure that messag
es are reached to their destinations and achieve the desired goal of the
application.
In this paper, we present an analysis of the performance of a number of major routing
protocols used in these networks which protocols AODV (Ad hoc On-Demand Distance
Vector), DSR (Dynamic Source Routing), and OLSR (Optimized link state routing). This
analysis is based on various parameters such as packet delivery ratio and end-to-end delay,
in order to find the best protocol can be used in the network with low density.
To achieve this purpose, we used a simulator OPNET_17.5. Depending on the
simulation results we have obtained and the analysis and comparison of these protocols at
different low density contract .We found that the protocol AODV is the best among the
studied protocols under the conditions set out in this study.
Many wireless sensor network applications like forest fire detection and environment
monitoring recommend making benefit from moving humans, vehicles, or animals to
enhance network performance. In this research, we had improved our previous protoco
l
(Dynamic Tree Routing DTR) in order to support mobility in a wireless sensor network.
First, we had mathematically approximated the speed threshold for mobile sensors, which
enables them to successfully associate with nearby coordinators. Second, we test our
(MDTR) protocol in a network with mobile sensors sending packets toward network's
main coordinator. The simulation results obtained from network Simulator (NS2) showed a
good approximation of speed threshold, and good performance of MDTR in term of delay,
throughput, and hop-count compared with AODV and MZBR Protocols.
