In this paper we investigate the problem of uneven energy consumption in a large class of
many-to-one sensor networks. In a many-to-one sensor network, all sensor nodes generate …

In multi-hop wireless sensor networks that are characterized by many-to-one traffic patterns,
problems related to energy imbalance among sensors often appear. When each node has a …

In the recent past, wireless sensor networks (WSN) have found their way into a wide variety
of applications, like animal monitoring, Vehicle monitoring, Machine monitoring and Medical …

Sensor networks have a wide range of potential, practical and useful applications. However,
there are issues that need to be addressed for efficient operation of sensor network systems …

Due to hardware, energy, cost and other physical constraints, sensor-based networks
present various design, implementation and deployment challenges. An analytical model is …

The hot spot problem is a typical byproduct of the many-to-one traffic pattern that
characterizes most wireless sensor networks: the nodes with the best channel to the sink are …

Networking unattended sensors is expected to have a significant impact on the efficiency of
many military and civil applications. Sensors in such systems are typically disposable and …

In a many-to-one sensor network, all sensor nodes generate CBR data and send them to a
single sink via multihop transmissions. Sensor nodes sitting around the sink need to relay …
