We present a review of the integer linear programming (ILP) formulations that have been
proposed for the routing and wavelength assignment problem in WDM optical networks …

Flexible-grid elastic optical networks (EONs) have attracted intensive research interests for
the agile spectrum management in the optical layer. Meanwhile, due to the relatively small …

In this paper, we propose a new data broadcast mechanism with network coding in
heterogeneous wireless networks. Our mechanism adaptively clusters the mobile hosts in …

We consider the routing and wavelength assignment (RWA) problem on wavelength division
multiplexing (WDM) networks without wavelength conversion. When the physical network …

Improving the performance of transportation network is a crucial task in traffic management.
In this paper, we start with a cooperative routing problem, which aims to minimize the …

In this paper, we study the routing and wavelength assignment (RWA) problem in a semi-
dynamic scenario where rearrangements are conducted in a series of sessions after traffic …

WDM optical networks are high speed networks and provide enormous capacity.
Survivability is very important issue in these networks. Survivability requires resources for …

We consider the routing and wavelength assignment problem on wavelength division
multiplexing networks without wavelength conversion. When the physical network and …

In this paper, we have proposed one wavelength assignment strategy for optical networks
which assigns the wavelength according to minimum connection count. The performance of …

All-optical WDM networks are characterised by multiple metrics (hop-count, cost, delay,
available band-width, loss probability, reliability), but generally routing algorithms only …
