In case of Military installations with a very small number of nodes, Mesh Network topology should be used. In fully interconnected Mesh topology, each node is connected by a dedicated point to point link to every node and thus the reliability is very high which is of prime importance in any military installations.

Mesh Topology is a network setup where each computer and network device is interconnected with one another, allowing for most transmissions to be distributed, even if one of the connections go down. It is a topology commonly used for wireless networks.

Even if one node fails, Mesh topology provides high degree of redundancy with each node connected to remaining nodes.

Advantages of mesh network are as follows:

• Mesh network topology yields the greatest amount of redundancy in the event that if one of the nodes fails, the network traffic can be redirected to another node.
• Network problems are easier to diagnose. Disadvantages of mesh network are as follows:
• Mesh networks are not very common because of its high cost of installation and maintenance.
• More cabling is required than any other configuration.
