An ad hoc network is a type of peer to peer wireless network mode where wireless devices communicate with each other directly, without the aid of a Wireless Access Point (WAP) device. Wireless networks typically depend on a base station or WAP device to manage and direct the stream of data between wireless devices. In …
ZigBee is a wireless protocol that was developed as an International standard to enable wireless, machine to machine communication, and networks. It is considered the catalyst for constructing “Smart” enabled buildings and homes since it is based on reliable network communications, a pro-longed battery life, and can be simply operated. The ZigBee Alliance is the …

A packet and a frame are both packages of data moving through a network. A packet exists at Layer 3 of the OSI Model, whereas a frame exists at Layer 2 of the OSI Model. Layer 2 is the Data Link Layer. The best known Data Link Layer protocol is Ethernet. Layer 3 is the …
The Session Layer is Layer 5 of the OSI (Open Systems Interconnection) Model of computer networking. The Session Layer is directly after the Transport Layer and before the Presentation Layer, allowing it to interact with applications as well as network components. The Session Layer is responsible for opening, maintaining, and closing all sessions between multiple …
VRRP stands for Virtual Router Redundancy Protocol. The VRRP is a commonly used method to avoid network outages during important data transfers. Data transfer can be highly susceptible to failure when sent by a single router network. To combat this problem, VRRP creates a virtual connection between routers within the same network and ties them …
