Alert: An Adaptive Low-Latency Event-Driven MAC Protocol for Wireless Sensor Networks
Table 1
Summary of features and assumptions of the Alert Protocol.
| Feature | Assumption or detail |
| Architecture | Single hop with a centralized base station. Base station is AC Powered | Transceiver | Only one transceiver in each node capable of switching frequency channels | Messages | Only one message by a node reporting an event | Number of nodes reporting events likely a subset of entire deployment | Events | Very rare, but correlated among neighboring nodes | Only one event report needs to reach the base station | Frequency table | Prespecified among nodes and switching pattern known to all nodes |
