*2.2.1 Applications*

Mesh network may comprise of mobile devices or stationary devices. Some of the applications of mesh networks which deserve communication are:


Voice over Internet Protocol (VoIP) is the main application of wireless mesh networks. In order to provide quality of service (QoS), wireless mesh network is used in telecommunication for voice communication. In current scenario, some of the applications where wireless mesh has been used include:

• From 2010 onward, Wi-Fi-enabled mesh routers are available in the market which is installable even in homes or at small workplace. Google Home, Google

on Hub, and Google Wi-Fi are various Wi-Fi wireless mesh networks.

• Iridium constellation with 66 satellites works under mesh network. This

The working principle of wireless mesh network is the same as that of the packets that travel around the wired internet data transfer between one node and another toward the destination [6]. This is implemented with the help of dynamic routing algorithm. It is possible by making each node communicate its routing information to other nodes within the network. With the received information, each node will decide whether to forward or to keep the data for itself. It is based on the functionality of the routing protocol. It is necessary for any routing algorithm to ensure that routing is done by predicting the shortest path between the source and destination. **Figure 4** shows the architecture of wireless mesh

Wireless mesh network can be connected with the existing network to provide effective communication. In traditional network comprises of various wired nodes, hotspots to communicate with the users, whereas in wireless mesh networks, the network is established with the help of various numbers of wireless nodes to com-

The wireless nodes used in wireless mesh networks play same role as wireless routers. Various Wi-Fi communication IEEE standards like IEEE 802.11a, 802.11b, and 802.11 g are used for wireless mesh communication. Nodes in the network are

topology connects various wireless links with other satellite. Voice calls can be communicated via mesh networks between one satellite and another across constellations without transferring the signal to the ground station. Latency is highly reduced by avoiding the signal transfer to the nearby mesh instead of
