Wireless Mesh Network (Ad Hoc Networks)

• A relay-based network enhancements, in
  metropolitan and wide-are environments.
• A simple and low-priced way to realize wireless
  MAN and WAN MP-to-MP, unicast, multicast and
  broadcast systems, with or without mobility.
• By plenty mesh nodes with shorter distances, high
  bit rate and ubiquitous communication can be
  facilitated.
• Technology domains
• physical layer, medium access layer, routing
  protocol, cross-layer optimization, system
  topologies, and infrastructure deployment.

Importance of WMN

• Facilitating broadband service.
• Robust and enhanced coverage.
• Low cost.
• Low initial investments and incremental
  deployment.
• Minimum cabling cost.
• High reliability.
• More mesh nodes, more reliable.
• WMN/Ad Hoc networks are the basis for
• WSN
• WBN
• WPN
• Home entertainment networks
