Krishnamurthy is a Senior Staff Engineer, Network Architecture
Lab, Intel Corporation, where he leads the projects in sensor
networks and mesh networking projects. The sensor network project
focuses on building heterogeneous sensor networks that use heterogeneity
to solve the scaling and resource constraints in this regime.
The team has built numerous applications including a conference
room finder and an interactive voting network. The project has
also built an Intel® XScale based reference design
for a sensor network gateway and Canby, the compactflash mote
NIC. Previously, Lakshman was an architect of Intels digital
television stack, where he contributed to the first nation wide
interactive TV broadcast trial with PBS. He received B.E. and
Ph.D. degrees from the University of Mysore, India and the University
of Kentucky, respectively.
near future, homes will be equipped with wireless networks that
bridge data and consumer electronics networks, interconnecting
desktop PCs, mobile laptops and handhelds, High Definition TVs
(HDTVs), DVD players, camcorders, and other multimedia devices.
This environment introduces new wireless network requirements,
including high and dependable bandwidth, low latency, and coverage
throughout the home. In a wireless home network today
a wireless-enabled device, such as a laptop, directly connects
to the network through an access point. This is known
as a single hop network. In the future, homes will use
multi-hop networks, also known as mesh networks, to connect
all the devices in the home to each other or to a broadband
connection. In a multi-hop network, a device can connect
to its destination through wireless routers, essentially taking
many hops to complete a data connection from the client device
to a broadband connection.
Multi-hop wireless technology offers unique benefits for creating
a high-speed, robust home wireless network. The benefits
over traditional infrastructure wireless networks include extending
coverage without requiring deployment of multiple wired base
stations, increasing utilization of spatial capacity to realize
higher throughput, and offering alternate communication paths
to provide failure recovery and better throughput. Intel R&D
is researching these self-organizing multi-hop wireless networks
for home environments.
This panel will discuss the evolution of wireless home networking,
the role of mesh networking, and the usage models that will
require this technology.
